code P1150 and P0125 at same time, suggestion to the mechanic

Question

The mechanic said it was the computer, but that is based on the assumption that the new sensor was ALSO good...as you said, it's possible to get a new one that is bad, especially since I ordered mine on Amazon (Denso part# 2349009 front A/F sensor upstream for California model 1998 Camry V6 motor, error code P1150).,,however these Denso's do not have any part # stamped on the part itself, only the box, so it's possible it could even be the wrong part, who knows...that's why I suggested swapping the front/rear upstream sensors..it would prove whether the problem really is the senor or not. I'm not ready to shell out $$ for a computer. The car is running quite well btw.

Answer 1

P1150 A/F (airflow) sensor circuit / range performance malfunction

P0125 Insufficient coolant operation for closed loop operation

This is the ECM when you get P0125 coolant operation for closed loop, this is definetly not a thermostat problem but the A/F circuit itself mainly the heater control, Where the A/F is not being seen by the ECM. Get the ECM at a salvage yard. it is less than a new A/F sensor.
