After looking at things as I suspected the water pump had failed so I headed to the parts store to buy a replacement. I decided to purchase an OBD2 code scanner also to find out what the code was. I got the water pump replaced and things seem fine and I hooked up the scanner and this is what I got.
P0155 02 heater circuit
HO2S-21 (Bank 2 Sensor 1) Heater Circuit Malfunction
It appears to maybe be an O2 sensor. If so, which one and where is it on this vehicle. Any help would be greatly appreciated.
have the same problem?
