20 Most Recent 2007 Chevrolet Cobalt Coupe Questions & Answers


First, you need to narrow down to the problem; why did the warning go off? This can be done by going to any repair shop and asking them to run a scan with a code reader. If the light still does not go away, do not worry. It takes a while to register the change, it may go away within a week. However, if that does not happen, you can try these steps:
• Turn the engine on and off thrice in a row
• Disconnect the battery, let it breathe and reconnect again • Reuse an OBD reader, maybe there is a new problem

I had this problem with a 2007 Chevy Cobalt. I changed the coolant sensor and even though the check engine light went out I still had a reading of "---" on the coolant gauge. The problem is most likely one of three things: a low coolant level, a bad coolant sensor, or the thermostat needs to be replaced. The only other possible thing it could be is a bad BCM (Body Control Module) which in that case you would most likely be having other weird problems.

The Thermostat and the sensor are both very easy to get to and replace. Take off the engine cover by removing the oil cap and they are both to the rear of the engine on the driver's side. They are right next to each other.

Hope this helps!

Probably a problem with the electronic throttle control , causing the PCM - engine computer to put the vehicle into a reduced power mode . Having it hooked up to a diagnostic scan tool to check for DTC'S - diagnostic trouble code an view sensor input data to the PCM should be the first step in the diagnostic procedure .

Were they pro level scan tools or cheap code readers? Cheap code readers can only read generic powertrain "P" codes P000X to P0800. You need a more expensive scan tool that's capable of reading "enhanced" or "manufacturer specific P1000 tp P3000 and B, C and U codes. However, if it says it can't communicate, that's an indication of a shorted module somewhere on the digital data bus

Your system is very complex and requires troubleshooting by an expert. I would trace the start signal from the switch then out of the bcm to the starter relay. See diagram below. I would also trace power from the park/neutral fuse thru the park/neutral switch.
