91 940se ECT sensor

Post by rickbrk »

I had a hard start when warm outside condition. I replaced the ect, the one under injector 3. It starts better when warm but now have a 224 code on pin #6 which says is a faulty ect or wiring. The sensor was from AutoZone. Should I find an oem bosch ect that came out or could it be something else?
Thank you

Did you verify that you purchased the correct sensor for LH2.4?

According to AutoZone it was the right part and there part number says it replaced the bosch part number that came off the car.
