    In the thread linked above, someone noted the MAF sensor as the culprit. You can explore that aspect yourself. If all your cylinders are misfiring, the cause is hopefully something other than a dead cylinder. I learned recently that the scanning process is not absolutely precise/perfect. The...

    Your ambient temps are way up there. I didn't know that there are two values. Do you happen to have stats for intake temp? I recall intake temp is higher than ambient because it is in an enclosed space. Would an excessively high value lead to a poor mix?

    1700 miles is a very short interval. It'd be great if your sample yields no potassium/sodium. If the values are high, then you can address the problem. Can you check under the rad cap too? Here are my two recent results from Blackstone showing coolant in oil. This level is not enough to impact...

    OBD2 faults all over the place?

    The app has been updated a couple of times in the last month and I think it doesn't tolerate my OBD2 devices any more. I am using a 4 amp maintainer to nurse the brand new battery. With the old device, it showed 14.3v which is consistent with the maintainer's flashing green light (full/max)...

    What have you done to your CX-3 today?

    Installed battery #4 on my 2017 this morning. Placed the order late last night. Item is in stock but the order was still being processed after 9:30 am. I wonder if they're saving battery pickups for later because most folks expect free installation and they're short staffed. Drove over, picked...

    CX-5 Battery Replacement recommendation?

    Thank you all for the recommendations! I decided to go with Duralast at AutoZone because of the 4 year warranty. By reading reviews on all eligible batteries, I realized that they all fail prematurely on some unfortunate consumers. I understand that there are other factors that contribute to the...

    There has got to be some significance with the brakes because of the different response that you noted. Does your OBD tool show any brake-related sensor/stats or do you know all that is involved in braking? Mine shows two: brake fluid pressure and brake switch, but there could be more on your...

    Warranty extension for fail-safe thermostat

    The two values on the CX3 are like this. Temp 2 (water B) is at the radiator. Temp 1 stays above 194 and below 214. ADD: The first pic shows the hour drive to Oakland in the morning via 237 and 880. Smooth flow at moderate speed until approaching Oakland. The second pic is the trip home from...

    Warranty extension for fail-safe thermostat

    Your charts for the stats at lower speed show a lot of fluctuation that don't really match the slight changes in speed. It went high up to 198 or so when the speed was still under 40. The dip to 170 in the middle also isn't justified. Temp 2 at the water pump is lower for pulling cooler fluid...

    Warranty extension for fail-safe thermostat

    They call it water temp sensor. 😅 18840C. One is on the driver side of the engine near 15-17Z the water control valve. The other is on the passenger side near 15-010 the water pump. I may be looking at the wrong diagram though, there are variations between US/Canada and Mexico, with or without CD.

    Warranty extension for fail-safe thermostat

    Can you look up coolant temp sensor on the parts diagram for your CX-5? That's how I found out that the second value (for CX-3) was for the radiator.

    Grounding Cylinder Head Test Results (2024 CX-5 Turbo)

    I thought he was really asking. 😅 Somewhere somehow there was a post or video saying that grounding to the transmission made a difference. I get the level of frustration tho. I am currently all the way up to my forehead in car troubles.

    OBD2 faults all over the place?

    I saved the list but didn't clear the codes while driving. They just went away on their own. The one for access system is saying that my key fob battery is low. Other apps (OBD Auto Doctor & Piston) didn't find any DTC. I can try a different dongle tomorrow. 😳

    CX-5 Battery Replacement recommendation?

    I checked my order history with AutoZone and it was a Duralast Gold/Flooded that I got in 2023. I recall not wanting the same one even if covered under warranty. It is either the Redtop at O'Reilly or Duralast Platinum AGM at AutoZone. 😵‍💫

    CX-5 Battery Replacement recommendation?

    Are you still happy with your RedTop? I am planning to pick one up from O'Reilly's tomorrow morning. The OEM battery went out after 6 years. Then a Diehard from AutoZone started leaking after 2 years (it had caps on top like the EverStart Max.) Now the Mighty Max from Amazon fails to hold a...

    Grounding Cylinder Head Test Results (2024 CX-5 Turbo)

    Thank you I will try again. Still need a new battery though. Soon after the maintainer was disconnected, the level fell to 12.0 (from 13.6) in less than a minute. I haven't had good luck with batteries after the OG died.

    No. More folks here are familiar with the multimeter like how familiar I am with chopsticks. 🙆
