So i'm getting the really fun, but wallet draining P0125 code. I know for sure it's my coolant temp sensor, because the O2s aren't failing and are reading correctly. I haven't replaced the thermostat, but the car isn't overheating.
I went to autozone and advance auto parts to get a Coolant temp sensor, and then both gave me a sensor that has a different plug! The sensor threads in correctly but I cant plug in the harness???
The harness on my car is black with a greenish looking inner connector. My stock sensor plugs in perfectly. The sensors I keep buying are similar, but the actual inner connector is more rounded.
I'm thinking of just splicing it in, but I don't want to go ricer style on the car and start hacking harnesses. It's just that getting 70 miles to 7 gallons is annoying as ####!
Anyone know what the hell is going on? Thanks!

UPDATE:
I finally found a coolant temp sensor that would fit and that is exactly the same as the one that was on the car. After careful searching, I found that the sensors the auto parts were trying to get me were wrong.
I changed the sensor, drove the car, and the check engine light came on again. Same code, P0125. Insufficient Coolant Temp. What's the next thing I should try and check? i'm thinking thermostat maybe? Or possibly o2? My idle stabilized quite a bit and I feel like I get a bit better gas mileages but it can be a placebo effect. the MPGs are still garbage.
