Cel p1141

[steve_protege]

Car threw this CEL on me (P1141): sensor 2 heater circuit voltage low. Anyone had similar issues with this and any tips to repair?

Replace the sensor pretty easy and simple fix

Could be the sensor is just carbon'd up and needs a cleaning. I had that code from one, cleaned it with maf or carb cleaner put it back in and no code. Still in car now and that has been a coupla yrs or more. Gas mileage still as good as ever. It was the 2nd one as well............

So assuming that it's just carboned up, how do I go about getting it off and cleaning? Where would it even be located? Mind you, on a 1.6 liter sedan.

Sounds like the one farthest away from the motor - code says sensor 2. Undo electrical connection and remove it from exhaust. All I did was spray the crap out it with carb cleaner, let it dry, put it back in & cleared code. Haven't had any issues since. If code comes back I'd say time for a new one. Worth a try IMO.

So here's a stab in the dark: Would a quarter sized hole in the exhaust system be the culprit for car running in opened loop mode all the time? Maybe would explain why I smell gasoline when the car is running/idling before stalling out?

Need help urgent ? I have a 1999 mazda familia with the zl-ve engine, its was automatic and i change it to manual (problems):i am missing my airflow box the part that the filter goes on the bottom half (it was stolen) it had a burnt knock sensor ,blown head gasket around the compression rights,and the gas needle moves every move i make depends on the turn are what ever i have a problems on hill (not my driving skills)when the gas is low are on the first mark,and it has a flat spot on move off if i push in the clutch and rev it will take of then die down immediately then pick back up again. Can anybody shine any light on this matter are know how i should ask?

So time for an update: Check engine came back on. Ran codes and now I have 6! P0102, P0103, P0113, P0123, P1504 and P1141. Is that a sign I'm better off replacing the wiring harness than trying to replace every sensor?

it is possible one or two issues are throwing multiple codes. Start a process of elimination. Fix the original codes first and work down the list

Well, just had the MAF sensor replaced last week.. I don't think that's installed wrong or anything.. Noticed my IAC sensor wasnt plugged in before, so plugged back in and first I've seen of the P1504 code..
