Question about Chevrolet HHR

1 Answer

HHR temp sensor Location. Did you ever figure out why, Temp Sensor was reading _ _ _, Mine just started doing that, then the engine light came on. I am going to check pin terminal connectors, before I replace part. It did start reading for a while and then went out again. Had problem on a 96 Dodge Dakota with terminal connectors on A/C pressure switches. Cleaned them and put back in service. I just have to find the location of temp sensor for sure. 2008 HHR looks like some kind of sensor right where the radiator hose connects to the water block of the engine.

SOURCE: 96 Ford truck engine lIght will not go away.

this is the problem with code readers they bwill tell you the code and sometimes even have a reset feature. However they do not tell you the parameters and don't have an drivability feature so you can not test the ecm and all the sensors or modules while engine is running. diagnostic scan tools are very expensive and hard to use unless you have been trained to do so and PEP BOYs is not what I call real reliable mechanics to begin with. Now I concure with toddG on his reasoning in what might be the potential fault. if your vehicle is running rich or lean your O2 sensor will pick this up on the exaust side, however it is not the sole sensor responsible for the ecm adjusting the fuel air mixture.. you stated that you have switched out several o2 sensors and the fuel pressure regulator, but there is also you mass air flow sensor, your TPS sensor, as well as your map sensor these are worth checking out and just because a faulty sensor is the problem doesn't mean you will get a code each time. the system is built with redundancy in order to keep the vehicle running. in order to get the best possible diagnois take it to a shop where they have a full diagnostic scanner this will have not only OBD1 and OBD2 but cam protocol as well. while the tech is scanning the vehicle he will be able to see how the engine is performing under realtime conditions. please rate this as well as change the rating for toddg because he did offer a valid suggestion

SOURCE: 1999 pontiac grand prix . will not run

If wiggling the wires cured the code, then one of the wires is broken inside the insulation. Pull on each wire one at a time. look for the colored insulation to stretch, this will be the broken wire. For the other car that wont rev up, this is a common when the catalytic concverter is plugged up. This will also cause MAF codes, and in turn, TRAC OFF light.

SOURCE: Temp sensor needs to be replaced

this does not mean the sensor is defective, it most likely means the engine thermostat is stuck open and the engine is not running hot enough to satisfy the computers preset temp requirements for minimum eng operating temp.

When I start the engine of my ford E150 v8, the temp guage goes immediatly to the warm range, when its cold. Is this the temp sensor? Is there a way I can figure out if this is the problem?


The easiest way to start diagnosing is disconnect temp. sensor connector and connect it to the good known sensor. If gage stays where it was, then this is not the sensor. Next step is to have electrical diagram of this model and see how exactly your gage is connected. It can be reading from ECM signal, or directly from that sensor. If it is direct reading, than it can be faulty gage or dashboard controller. In case it connected to ECM it can be incorrect ECM output (which very unusual).

2006 HHR, check engine light came on, the engine coolant temperature gauge stays at 0 and the coolant link on my panel just shows ----F. Also my remote start won't work


Your coolant temp sensor is not registering. It probably set a trouble code, that's why your remote vehicle start is not working. The temp sensor is located at the rear corner of the engine block on the back side of the engine. This will be the corner of the engine closest to the driver. The temp sensor may be faulty, unlugged or there could be problem in the circuit. Even if you find the sensor unplugged and you plug it in, the code will have to be cleared before the remote vehicle start works again.

2006 HHR my a/c stopped working and the engine coolant temp guage reads blank at the same time suddenly


check to see if the cooling fan is working and if is not then ac pressure gets to high and clutch shuts down. you may have bad temp sensor or relay.

2006 Chevrolet HHR LT Problem


After searching around, I found several posts that suggested reseating all the relays and fuses under the hood. After checking, I noticed nearly all of them were not seated well. I pushed them all down and I haven't had the problem since.

2001 Kia Optima over heating


I figured this out and fixed it on my 2001 Optima. Mine was an electrical problem, not an overheating problem. The problem shows up when there is a heavier than normal load on the electrical system. For most of us, this is when the air conditioner is running full-blast on a hot summer day. However, it was also occuring when I ran the heater full blast. The heater running full-blast should have lowered the temperature, not raise it. So I tested the coolant temp while the gauge was showing it overheating. The coolant temp was not increasing, but the gauge showed that it was. It is caused by a bad ground connection. Another test you can do to see if your problem is the same as mine is this. As soon as the engine is showing overheating, pull over, park the car and turn off the engine. Immediately start the engine again and see what the temp gauge shows. If it still shows hot, you'll know you've really got overheating coolant. If it goes back to normal range, you'll know it's just a bad ground connection. Turning off the engine eliminates the resistance in the electrical system that has beeen building up and causing an erroneous high temp reading.

To fix: Either find and clean ground connections throughout the vehicle until it fixes it, or do what I did. A mechanic at the Kia dealer showed me this. I ran a new wire from an empty bolt-hole on the top of the engine to a bolt into the frame behind the engine. I only added a 6 inch wire and a new bolt into the top of the engine. The bolt into the frame was already there, so I just removed it, put the wire under it, and replaced the bolt. It created a redundant ground that prevented the build-up of resistance that caused the erroneous temp reading. It was a 5 minute fix and it has never done it again. Kia knows about this problem and they put out a post to their shops on how to fix it.
