I have an 01 gs430 and I am getting the p0155 o2 Sensor heater circuit code. Usually as I have read on the forum it tells which bank etc. Mine does not. is this a generic code for another issue? thanks guys!
9/10 it is the sensor, but do check your connector. My friend just threw a o2 heater code in his IS300 and it was a bad connection. One of the pins was shoved back in the harness.
p0155 with no location?
