SOURCE: i have my check engine light on and a p0031 error

On toyotas this is almost always a failed o2 period. Take it somewhere and have it put in. On v6's it is not that easy to get to.

I would check the O2 sensor, and if it checks bad, replace it, and clear the trouble codes. If the light comes back on, you may need to check further. .

Got code Po240

Hi there! Before changing any O2 sensor I would first look for vaccum leaks on the engine. It is not usual for a car that year to have a bad O2 Sensor. Any air that is entering the intake part of the engine without being measured will affect O2 sensor readings.

Bank one sensor one is on the side with cylinder one and before the catalytic converter.
Please be aware the code is for the heater circuit which may mean the sensor is bad, or the sensor may be ok and the problem is in the heater circuit.

Sounds like there is an issue with the heater on the bank 1 sensor 1 O2 sensor. Bank one is the same side of the engine as the number one cylinder and sensor one is always before the catalytic converter. Check for battery voltage on the black with yellow wire with the key on. There should be twelve volts. Check the heater circuit of the O2 sensor with an ohm meter. Unplug the O2 sensor connector and measure resistance on the sensor side of the connector that the blue with black and black with yellow wire go to. Off the top of my head it should be around 14 ohms. You can confirm this by checking the heater circuit on the bank 2 O2 sensor. If there is voltage and the heater circuit doesn't ohm out than replace the O2 sensor. Let me know if you have any questions and I'll do my best to answer them. Thank you for using!

Engine light comes on with code p1135 control fuel air metering. how do i fix this?

P1135: A/F Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)

Your first O2 sensor is not getting heated either because the wiring to the sensor is bad or the heater inside the sensor is bad. If you have a four cylinder this would be the only O2 sensor you have before the catalyst. I would just replace the sensor, clear the code, and see if it comes back.

Check engine light came on.

P1135 means that your O2 sensor has gone bad. The O2 sensor on the Toyota's are called Air fuel sensor's. If you have a 4 cylinder engine, the O2 is on the exhaust down pipe before the catalytic converter, and if it's a V6 it the O2 sensor on the fire wall side along the down pipe from the exhaust manifold. (sensor 1, bank 1) Good luck and keep me posted, check the wire harness. The wire harness could have corroded or burnt from the exhaust, but most likely it's going to be a bad O2. Keep me posted ,be glad to help
