Camshaft Sensor Problem
 

How many camshaft sensors are there on a 2007 HHR 2.2 L DOHC?

:welcome8: to the forum G Hammonds!

There are two sensors, one on the intake cam, and one on the exhaust cam.

Give this thread a read, it covers replacing them along with a ton of great tips. Just click the link below.......

No, that link is for the Solenoids - not sensors.

For OP - the title says Camshaft Sensor Problem - that does not tell anyone here any information at all. If you are looking for advice, or suggestions on resolving a specific problem, you need to provide additional information, including any info on the Check Engine Light being lit, as well as the subsequent codes stored therein.

You're exactly right whopper, my apologies to the OP, please disregard the link.

2007 hhr cam sensors
 

I have just replaced a cam sensor at the drivers side just under the fuel rail, is there another one somewhere?

Umm. Did you read the rest of this thread? Especially post#2.

Yes there is another on the exhaust side. I believe it's passenger side rear of engine.

Oh, and check your PM.
