I have a Camry 2000 LE V6, it has done 65000 miles. I got brake job done, replacing all 4 rotors and pads. I take out the car out of garage, and after a few miles, i get Check engine light. i check the code, it's P1150. Is it purely co-incidental that the check engine light is on, soon after the brake job?

I have got o2 sensor replaced once at about 30,000 miles. How many A/F sensors are there in this model?
Any guidance will be helpful.

P1150 A/F sensor Bank 2, Sensor 1.

This is the first sensor on the exhaust system coming from the cylinder head nearest the front of the car (radiator).

The sensor output voltage is either not changing or outside the norm.

The computer is detecting the A/F voltage t be 2.8V or less or 3.8V or more.

Or it stays at 3.30V and does not change.

Or there is a problem with the wiring to the sensor.

Someone with an ODBII code reader with real time output can measure the sensor voltage as the engine is running. Then verify the voltages and confirm it is bad.

You may be able to see the sensor with the hood open. It is a long way from the brake area. Make sure the wiring connector to the sensor is still attached.

Did you replace all the sensors. The engine has at least 3 maybe 4/5.

This is a California emissions standard car, if replacing the sensor make sure to use a one for a California emissions car (not Federal). Suggest using Denso or Toyota brand and a OEM type vrs a universal (one size fits all) sensor.

 

Did the mechanics that did your brake work also do any fuel injection services while it was there. EFI services are notorious for ruining cats and O2 sensors. If so, the repair shop may be liable for damage caused by it's product.
