Did you reset the Computer after you did the repair? After you replace a sensor that has stored a fault code you need to reset the computer in the car to clear the stored codes. Auto Zone or O'Rielley's may do it for you or try removing the Negative battery terminal for 60 secs.

Engine light code p171 comes up. I recently changed the air flow sensor. Everything else is working fine. What can this be in a Toyota Corolla 2003?


DTC P0171 is set when fuel trim is driven rich beyond a certain value. Possible causes are:
1. Exhaust system leak.
2. Improper fuel pressure.
3. Fuel injector restricted.
4. Defective heated oxygen sensor No. 1.
5. Defective Manifold Absolute Pressure (MAP) sensor.
6. Defective Engine Coolant Temperature (ECT) sensor.

System Too Lean. This code will set when an air fuel ratio sensor (O2 sensor) gets lazy.

Also, check for a vacuum leak on that side.

Hi Team, Good Afternoon. I purchased a 2005 Toyota Corolla 1 month ago (Used Car). As soon as I got the car I got the check Engine light. I took the car to Toyota of Irving and they told me that it was...


Did you buy this from a dealer? if so, you should have taken it back ASAP I dont know why you didnt have the Toyota Dealer fix the car, now your in the middle of a mess, getting 2 shops involved, and the car still has a problem. When you bought the car, whoever you bought it from, knew there was a problem, cleared the code and it took a while for the check engine light to come back on. So now you will just have to pay someont to fix the car. The trans shop told you it needed a converter and solenoid, the problem is still there, so make it their problem. I think you need someone who knows toyota . theres no recall that I know of. Recalls are free, anyhow. . ecm is warranteed 8 years or 80k miles. Have the dealer check it out. Have them Check Bulletin TC008-04 and T-SB-0378-08

Hello


I am wondering if this is a faulty temperature switch or cooling fan switch. They control the cooling fan operation, and could explain the up and down of the temperature gauge if not working properly.
