2007 pontiac, solstice cam sensor replacement -is this common?

Google it/utube /forum Pontiac

get an OFFICIAL diagnosis from someone with a much more sophisticated reader. It doesn't have to be the dealer... just a good mech that specializes in GM

The Low Coolant is part of the Overflow Bottle, Check the Plug and if the plug is good, you will need to replace the Bottle. you can find a bottle for less than $100

More than likely you need to replace the cam phaser itself it only comes on do to lack of oil pressure to the motor ( like not changing your oil regular or running the car extremely low on oil)

Take it back to the dealer and get them to fix the problem they created.

This is a fuel leak code, could be cap is leaking or may be sign of a bad fuel pump. Try replacing cap first

Still have coolant leaving the exhaust,
means the problem wasn't diagnosed &
repaired properly


Not too many choices there

Head Gasket,intake,cracked head

Sounds like the head gasket wasn't
the only issue,something was missed
during the last reapair

- Engine Control Module (ECM) Tech notes The most common cause it the three way catalyst converter Bank 1. Changing just the O2 sensor usually don't repair the problem. If the P0420 code is combined with other codes, try fixing the other codes first.

Check the mass air flow sensor

If you unplug the MAF sensor it should run using the default mapping. I'm having the same problem, but I want to figure out why it won't run with the sensor connected.
