What is the code for the villager check engine light?
Hi As title states my 97 mercury villager has check engine light with code P0135 – Heater circuit O2 bank 1 sensor 1. Following has been performed: – check power to sensor – OK – reset code and same code returns – replace with new (upstream) O2 sensor – same code returns At this point the shop sa…
What causes an oxygen sensor to set p0135?
The ECM tracks how long it takes for the oxygen sensor to begin switching. It the ECM determines (based on coolant temp) that too much time elapsed before the oxygen sensor began operating properly, it will set P0135. You will likely notice poor fuel economy the illumination of the MIL.
What are the trouble codes for an oxygen sensor?
This article will help you to diagnose diagnostic trouble codes: P0135, P0141, P0155, P0161. All of these trouble codes have to do with a malfunction in the oxygen sensor’s heater or it’s circuit. Contents of this tutorial: Important Suggestions And Tips. Symptoms Of A BAD Oxygen Sensor.
Is the downdraft O2 sensor still coding for p0141?
Ok, so far I have replaced the downdraft O2 sensor TWICE, replaced the catalytic convertor, replaced the updraft O2 sensor and done a set of plugs and wires. The car is still coding for p0141 downdraft O2 sensor failure. It is a 2000 Ford Focus SE. Can ANYONE tell me what else this could POSSIBLY…

What does p0135, p0141, and p0161 mean?
Won’t pass state mandated emission testing. As mentioned at the beginning of the article, P0135, P0141, P0155, and P0161 DTCs share one specific and common thread: a Heater Circuit Malfunction. What does this mean? Before I jump into an explanation of what the codes mean I’ll share with you some basic working theory of how the O2 sensor works.
Why is my O2 sensor on my MR2 not working?
My 2000 MR2 has had an O2 sensor out for a long time with no apparent driveability troubles, but recently it has a rougher idle, hesistates on acceleration, some detonation, and most recently doesn’t want to start when it is hot. Cranks but won’t fire until cooled down. I check and got codes P0171…
