check engine light rh reflash

Post by vtecboi »

Just plugged in my race header flash ecu today and I've turned the car on and off several times and been driving for several hours and the light is still on. I stopped by advance auto and they said it was the oxygen sensor closest to the motor. This is the sensor disabled by the flash right? Is there some type of reset to get that light off?

No, only the secondary o2 sensor is disabled. The primary sensor still reads or it will not run in closed loop. The sensor has probably been damaged from vibration or a wired has ben pulled too tight.

Why do you think it has been damaged? The light came on about 5mins after I installed my rh. If I had pulled a wire during installation the light would have come on immediately right?

Thanks for the quick response.

You need to follow the factory service manual troubleshooting steps for the error code you are getting. The reflash is not the cause of the error code.
