Hi folks... well this is a new one for me. CEL comes on with odd codes. UO415 invalid data from ABS control module. PO500 Vehicle speed sensor A, PO 504 Brake switch A/B correlation. Even stranger, I start the car from a cold start to find out my coolant temp reading 130F after 5 min it reads 150F which I know it’s wrong due to the cold start up. Any suggestions? I’m thinking the coolant temp sensor has gone bad...


these readings were from Torque PRO and OBD Fusion apps

 

Can someone help me find the location of the coolant temp sensor? Thank you

 

ECT is #1

 

The coolant temp sender is in the plastic thermostat housing on NA 4.2L engines.
