p0117 -- Coolant temp
Find your temp sensor and trace the wires. Make sure it is hooked up. Replace the sensor. Circuit is low meaning it is a dead sensor or does not have enough power to it.

p0166 -- Rear o2
Double check this is your code since this is typical on cars with multiple banks and we only have one. This is found on cars that have the V or boxer shape.
Regardless, check your rear o2 harness. do you have a cat?

p1406 -- EGR recirc code
Good luck. We do not have EGR valves.


With you having two codes that are not indicative of a cobalt, I would check your PCM. It should say E69 on it somewhere. If not run the part number on it through google.
You may need to flash a tune on the car as well.

Something is funky with your car....

Exactly where would the temp sensors be located on this car? I am carless. Been for 5 years plus. And everyone is saying we don't have have egr valve. Makes me want to pull out my hair. I need to get a inspection ASAP

We also do not have bank 2 rear o2 sensors.

From the manual it looks like it is on the rear passenger side of the engine in between the heater hose inlet and outlet on the thermostat Housing.

If it is plugged in and wiring is good, replace the sensor. If its still having that issue, you may have a thermostat problem, PCM issue related to those other two codes, or a massive air pocket in the cooling system.

Does the dash read --- under coolant temp?

jaygo7007

It doesn't read under coolant temp. But it do say low coolant. Just pop the hood and seen its low though

Bleed your cooling system then.....

If you have been driving the car on coolant low enough to make the sensor not be able to get a reading you just may be needing another rebuild.....

jaygo7007

I haven't been driving it except the first day I got it out the shop. I drove it from the shop to home. I was real easy on it. Didn't go no faster than 40 mph

jaygo7007

My bad wrong code its not a p1066. Its actually p0116

That changes nothing about what I just said.

You better pray that your coolant being low wasnt the cause of that code. Get to checking the other things I said.

p0116 goes with the p0117. Same path of diagnoses for both of them. It is unplugged, dead, has a broken wire, or coolant is too low/not bled and has air stuck on it. It wont read air temps.

jaygo7007

Everything seems plugged. So I'm guessing dead wire. I'm looking for a shop to bleed the system and refill. Cause I'm guessing just adding coolant won't fix it even though the coolant tank is low. Like I say the car has been for a year and half.

Open the coolant tank. Fill coolant. Start car. Add coolant as it drops. Replace cap.

jaygo7007

Added coolant. Let it idle for a while. Drove it around the apartment complex. I went to add more coolant but it didn't need any. So I went across the street to advanced auto parts to get the codes pulled again. Still have p0017 and p0016. Now I also have p0243. Something about turbo or supercharger solenoid.
