Code 42 is a problem with the heater circuit for the O2 sensor number 3. That is usually the sensor after the catalytic converter.
The heater is not working which could be a faulty sensor or a problem with the power circuit going to the sensor.

I have an 06 g6 gtp, today the car shut off on me and wouldn't start back up all that happened was the check engine light came on. Now my key less entry will not work on either control I have and I tried...


if I were you, I'd have the dealer reprogram the theft/fob system. perhaps another driver locked your car inadvertently with a code similar to yours.

Remote start will not let car start


The remote start won't keep the car from starting.

If you have a check engine light on currently, that will not allow the remote start to function at all.
