What have you done to your P5 today?

Well, I checked my knock sensor and it's pretty much goop-less.

I think there was goop in there at one time because I can feel a little "stickiness" at the lower edge of the sensor.

FYI - Throwing no codes and no pinging as far as I can tell.

I'm wondering if I should attempt to replace it of fill it up with something like RTV gasket sealant?

I'm pretty sure I can put some RTV on my finger and reach up between stuff and wipe it into the back of the sensor.

---Or---

I could wait until my son comes back home at the end of the month so he can "assist" me so then he will see how he can get at things on the back of the engine once the side-to-side 5-bolt crossmember is removed.

What'cha think? :unsure:
I saw a post a few days back on the Facebook Protege5 Group where a guy had refilled his. I can't remember what he used as filler or if anyone commented on whether that was a good/bad idea, and now I can't find the post.

I went and ordered one from Amazon and will do it together with my son when he comes home later this month to swap out cars.

The Product Description Section (lower down in the listing) has some good info on how it functions.

And its cheap...err...inexpensive. :)

I think that you are better off with the new one.

Your old one may be out of spec without the goo and from age, and silicone may not be the proper stuff to use.
The goo may be used as a "suspension" for the sensor and its viscosity may be important.

I'm pretty sure regular silicone doesn't melt.


I found this...
It's the range/performance code P0326 that our car doesn't have.

Our ECU's don't know if they are getting inaccurate knock sensor data.



"The sensor signal wire informs the PCM when a knock occurs and in what degree of severity. The PCM will retard the spark timing to avoid pre-detonation. Most PCMs have the ability to learn spark knock trends in the engine during normal operation. If the PCM determines that the knock is out of the ordinary or that the noise level is abnormally high, P0326 may set. If the PCM senses that the knock is severe and cannot be eliminated by retarding the spark timing, P0326 may set. Keep in mind that knock sensors cannot distinguish between a knock from pre-detonation or one from engine problems."


If your old sensor has become overactive, your engine may be in a constant state of having its timing retarded.
 
My car didn't come with a key fob so I checked with Mazda, and they wanted $184 CAD each.
F-that.

I ended up at a wrecker a few years later where I got two key fobs (as well as a whole bunch of screws, bolts, clips, fuses and such), for ten bucks.

I don't use my key fobs anymore.

They're not waterproof and I have a tendency to fall in the water. Lol
 
The wireless receiver module is up under the dash on the drivers side closer to the door.

I'm talking about these things...


20210823_231507.jpg



That's about $624 CAD with tax for the three of them at full new OEM replacement pricing. Lol


Each one of these key fobs is worth as much as my entire car. Lol
 
All you need is the FCC ID of our remote and you can have combo key or flip key or stay with oem setup. I used the board out of our oem remote inside a flip key shell.......

had a shell drilled for panic button but went without panic because it was too easy to hit so on the one without panic just removed the panic part of the membrane that had that button. Panic shell below......

.........and for my Scion xB I found a combo key and the board of the combo key fit inside a denso flip key shell so I have all 3 setups for it.

20210329_165415.jpg


....this is gonna make me find a combo key for the car now......thanks, lol


FCC ID for our remotes = KPU41704..........searching...........


O Kayyyy.......initial search = SOL except for oem replacement fob. I'll retract the combo key option for now, but I did make and have a working flip key. Wish there was a combo key like for the xB that had the P5 FCC ID............sux because P5 is 2003 and xB is 2004, figured there would be one for the P5 too.............

Been using a flip key like that since about 2011! Love the flip key vs separate key and fob
 
Yeah, have had mine quite awhile too....no keys on it, mostly just novelty use here and there. I wanted to find a combo key for it like I use for the xB. That is my preferred setup. Oh well, xB is the daily driver anyway.


On that note...... According to the inspection station I have used for last 10yrs during my inspection this year, the P5 only has 4000 miles more than it did in 2011.......not zackly living up to my username, lol.....

Whaaaaaaaaat?!?? That's a thing? I want a flip key now! Can I buy one and program it to my car? Sorry maybe you already said that it can be done, but I probably missed it. Need to do this kinda research already for my dad's Tundra, so I might as well learn how it works for my Protege too!

meanwhile mine is mostly rust and at 262k miles. It isnt the daily anymore. Intown driver only these days.
 
I have a "low profile" dipstick just like yours (and kinda like it that way).

Years ago, and oil change place down the street from me broke off my dipstick handle. I found out when I went to check the oil and found that it had been taped back on; came off right in my hand with remnants of engine-baked cellophane tape on it. The shop had cracked my accordion air intake as well on the bottom and the engine was getting unmetered air. I took it back and the manager took responsibility.

Prior to that, an oil change/car wash place in an expensive neighborhood (with fancy cars) left my oil filler cap off. I found that a month later, and the filler cap had been left sitting next to the hood latch. Amazingly, the car had lost no oil, but there was an oil sheen *everywhere* under the hood. The shop detailed my engine and paid to replace the under-hood insulation.

Last year, yet another oil change place didn't install my drain plug properly and I toasted my engine on the highway after the plug flew out. Took three months, but the shop paid for a JDM replacement for it. My buddy walked by the shop the other day and saw a P5 in their bay and he almost ran over to warn the owner. :D I got a coupon from them just a few days ago that said "Under new ownership" on it.

I don't change my own oil here at the apartment out of fear of a mess. I'll start doing it again when I buy a house. For now, I hunt for dealership coupons and don't drive either of my Mazdas all that much. Oh, and I did the free oil change for school/university employees just the other day at the Mazda dealership - no Mazda required. EDIT: That offer is good to the end of September, btw.

Hey, but that's not a bad place to be actually. It doesn't have to be a reliable daily right? So who cares if it breaks down for a bit or isn't super nice.

Mine is a daily and it's probably in slightly better condition, but it's still old and worn, and I have no second car. I have a small heart attack at every little noise. Been pretty blessed with reliability so far though.

Speaking of old and worn, my EGT insufficient flow CEL came back on. I don't remember the code because I cleared it immediately, but I think it was a p0402 maybe? I'm going to need to start thinking about cleaning the EGT or replacing it with a Canadian market one, according to PCB. I've heard people say it's hard to access? I'm going to take a nice stroll through the factory service manual to find some diagrams.

Aaand this is why I have trust issues with those kinds of places. I followed your engine replacement thread pretty closely and it was certainly one of the more theatrical threads I've followed on this forum.

I can think of quite a few similar stories from friends and family as well. My dad always changed his own oil and taught me to do so as well. My parents even bought an old Toyota a few years back that had lifetime oil changes at the dealership and he still changed the oil himself.

That would be your EGR.

It sounds like it may be getting sticky.
If it gets really bad, your car won't run.
If you are burning a lot of oil, things get worse because the exhaust running through the EGR valve is full of oil that sticks to the EGR and gums it up.

The EGR valve is much like a solenoid valve that allows exhaust gas to get into the intake to reduce engine temperature and pollution, but an EGR valve can be closed, open, or 3-4 steps of partially open.
It's also called a step motor, that opens the valve in increments.

The "Canadian" EGR isn't listed at Rockauto for the Protege5 but it is listed for the 2L Protege.

It has nothing to do with Canadian or American emissions.
Canada has a generally colder climate and the EGRs were failing first in Canada because a cold EGR will have exhaust gunk condense inside of it.
They made a new EGR with coolant lines attached to warm up the EGR and it was first introduced in Canada.
(A lot of Americans were phoning Canadian Mazda dealers to have the Canadian EGR shipped to them. It wasn't available in the USA for a while.)

You'll need a stubby 1/4" ratchet handle and socket to remove it, and I believe that you need the JIS screwdriver to take it apart to clean it.

I remember one guy said he put his car in gear and pushed it a bit then hit the P-brake.
That rolled the engine in the engine bay a little bit on it's mounts and gave him a little bit more room to get in there with his 1/4" stubby drive.



Thread 'EGR question.' EGR question.



You may be able to simply remove and clean your EGR, or replace it with a regular EGR if you're not burning a ton of oil and your winters aren't terribly cold.

The Canadian EGR is a lot more money and is a PITA to install.


My car has 245,000 km on it with the original EGR that is still working fine.
My car doesn't burn any oil though and I don't drive aggressively. (which I assume can foul up the EGR?)

As always, loads of good info from you, PCB! This is exactly what I was looking for.

I do recall hearing that the EGR can cause the car to run poorly. It could totally be a placebo effect, but mine does seem to run a little rough now, and I can actually see the RPM needle moving up and down at idle. Not sure if that's normal.

I believe my code might have been a p0401, as I recall it saying something about insufficient flow. I've seen and cleared the code probably half a dozen times now, but only recently has it begun to trigger the CEL. I would only see it coincidentally while using my OBDII reader to do MPG on trips. Now that I think about it, It has only ever tripped the CEL on cold mornings when I am up early. ("Cold" being relative, our low's right now are in the low 50s.) It's only going to get colder here over winter though.

I will see if I can find the EGR to remove and clean it. Just need to dig up those diagrams.
