Trying to identify location of coolant temperature sensor. CEL came on and is throwing P0128. Temp gauge seems lower than normal (~1/3 mark). Car runs fine. Heater works fine. Coolant temperature level OK.

Went ahead and ordered replacement part, but can figure out where the heck it is located on the engine.

Can anyone point me to the right location?

Thanks!

 

Backside of the block near firewall on coolant crossover. Btw this isn't your issue. Make sure your coolant level is ok. You may have a leaking water pump or thermostat issue.

 

Thanks Wht95scort!

Reset and now P0128 is coming back with additional codes: P0101, P0175, P0172. Any ideas on what the issue might be?

I cleaned the MAF sensor and I will probably also install the new ECT (since I already bought it).

Thanks again.
