2001 Toyota Tundra Code P1135

P1135 TOYOTA code description Air-Fuel Ratio AFsensor need to reach a minimum operating temperature of 1200 degrees F to produce an accurate voltage signal.

2001 toyota tundra code p1135. P1135 mean airfuel sensor heater circuit response bank 1 sensor 1 Its the airfuel sensor upstream between the manifold and engine. 2001 TOYOTA 4 RUNNER HAS A CODE 1135 BANK 1 SENSOR 1. Based on the output voltage the Engine Control Module determines if the air-fuel ratio is RICH or LEAN and adjusts the stoichiometric air-fuel ratioThe ECM also checks the fuel injection volume compensation value to check if the AF sensor is deteriorating or not.

I had no idea what it was related to but knew I was due for an oil change. I have changed my P1155 sensorit took about 35 seconds obviously some exageration here my new code is P1135 since changing the front radiator side AF and as yet I have not come up with a workable approach and am running out of tiime on my emissions test. To double check I stopped by AutoZone who hooked it up and got a P1135 error code.

The the mains are huge. P1135 AirFuel Sensor Heater Circuit Response Bank 1 Sensor 1 is correct. P1135 mean airfuel sensor heater circuit response bank 1sensor 1 Its the airfuel sensor upstream between the manifoldand engine.

Bad Oxygen Sensor The oxygen sensor itself is one of the most likely reasons that P0135 is triggering your service engine soon light. P0125 is usually caused by a bad thermostat low coolant or a bad ECT sensor. I replaced air filter oil filter oil and the light went out.

We found out that the code is for Air Fuel Sensor Heater Circuit Response. The day I changed O 2 sensor 1 upstream for my 2001 Toyota Camry 4 cylinder 22L the code was cleaned and then the engine light went away. The airfuel ratio sensor needs to reach a certain operating temperature a minimum of 1200 degrees Fahrenheit to create accurate voltage signals.

The faster the air-fuel ratio sensor reaches that temperature the faster the sensor will start sending an. According to the Service Manual for a 2000 5VZ-FE same engine I think the P0125 code actually has nothing to do with the coolant temp even though thats the name of the code. The check engine light came on my 2001 Tacoma Double Cab 4x4 SR5 V6 this weekend.
