2001 Toyota Tundra Code P1135

Where is the ects relay on 2001 tundra.

2001 toyota tundra code p1135. I had the same code since 2010 until 2013. P1133 TOYOTA code description The Air-Fuel ratio AF sensor varies its output voltage in proportion to the air-fuel ratio. The airfuel ratio sensor needs to reach a certain operating temperature a minimum of 1200 degrees Fahrenheit to create accurate voltage signals.

P1135 mean airfuel sensor heater circuit response bank 1sensor 1 Its the airfuel sensor upstream between the manifoldand engine. Open or short in AF sensor bank 1 sensor 1 AF sensor bank 1 sensor. The vehicle I worked on was a 2001 Tundra 2WD Automatic 34L V6.

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. It cost about 179 at a reputable auto parts store. I own a 2001 Toyota Tacoma 34 L engine and CA emissions.

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. To double check I stopped by AutoZone who hooked it up and got a P1135 error code. The P1135 and P1155 are specific Toyota codes for the same heated airfuel sensor but on opposite sides of the engine.

I replaced air filter oil filter oil and the light went out. P1135 AirFuel Sensor Heater Circuit Response Bank 1 Sensor 1 is correct. If your Toyota Tundra has registered it means that the ECMPCM is getting a signal from the engine coolant temperature sensor ECT that the engine is not warm enough to enter closed loop fuel control.

A pro never guesses we use a magic 8 tool walfart called volt meter to find them. The CEL light is on and OBD code is P1135 which is a AirFuel Sensor Heater Circuit Malfunction. The faster the air-fuel ratio sensor reaches that temperature the faster the sensor will start sending an.
