Question

I got the codes P1130 and P1135 on the 1997 Toyota Camry, do the codes have to do something with the cooling heat sensor? How can we fix it? Does it have anything to do with the cooling heat sensor in the radiator? My additional fan is always on. please advise.

Answer 1

Hi there,

Actually both of these codes point to the front O2 sensor being the problem. The heater circuit in the sensor has failed and that brings these codes. You may not actually notice a difference in the way the car runs with this code because eventualy the sensor get's hot enough that the heater is required. It can affect the gas mileage.
