Hi, I have a 2002 Toyota Camry LE V6 which started to display a check engine light today. In checking the fault code, it shows up as P1135.

Air fuel ratio sensor - heater circuit

For the location it seems to be Bank 1 Sensor 1. The problem is that it is hard to find any info on where that corresponds to the engine. From what I know, there is 1 sensor on the front of the engine, and one on the back, but the bank 1 sensor 1 info is not very descriptive in figuring out which sensor to replace.


P1135 DTC: Camshaft position (CMP) actuator, intake, Bank 2 (trouble code is at the bottom of the page)

In looking up compatible parts from Denso, I get 2 results

Denso 234-9047

Denso 234-9042

Overall, I am trying to figure out which sensor I have to replace.

 

This may sound different but I had some PO171 AND PO174 air fuel codes I could not get rid of for a long time. Long story short wound up cleaning air intake. Problem solved. There is a special spray. Check oreillys or other stores. Google how to clean depending if you have automatic or manual butterfly. My butterfly was filthy and not operating correctly.

 

Bank 1 is the rear cylinder bank. Sensor 1 is the first sensor on the exhaust system coming off that head. Its location is before the emissions converter.

You want upstream (before converter), rear (rear cylinder bank) which is 234-9047.

Shop the internet for the lowest prices.

 

Thanks, I will work on getting that, and see if it can be accessed without having to go under the car.

 

More strange issues. Due to all of the snow and the location of the sensor, I am not able to get to it, so I went to a mechanic shop to get an estimate on how much they would charge.

After they used their OBDII tool to pull error codes, I suddenly got 2 additional warning lights

VSC and TRAC OFF

The button corresponding to the traction control does not respond, and those lights do not produce any additional error codes.

If check light is on, VSC and TRAC are programmed to turn off.

Fix the error code problems and when the check light turns off, so will the other lights.

 

Managed to get everything fixed. The VSC and trac off was caused by a C1336 error.

I had to short pins 4 and 14 on the car to reset it.

Not sure what caused it.

 

Yaw rate accelerator calibration.

If the two lights came on after checking codes, it happens some readers are incompatible and will this problem.

 

If you dont mind me asking How did you get the P1135 code fixed?

 

Thread is about C1336.
