3 Codes pulled
I just copied and pasted my last post from the other thread b/c the original thread got moved to the introductions page.
Well this weekend I was able to pull some codes with the scanner....
1)P01491-Rad Fan Control Relay Circuit An open or shorted condition detected in the radiator fan control relay control circuit. This includes PWM solid state relays.
2)P01494- Leak Detection Pump Sw or Mechanical Fault Incorrect input state detected for the Leak Detection Pump (LDP) pressure switch.
3)P01555-O2 Sensor Heater Failure Oxygen sensor heater element malfunction
The descriptions I just got from the stickies so I don't completely understand what they mean but obviously something is wrong with my cooling system..... maybe a hose is broken somewhere? and the water pump is bad? any help?
