Well I really need to smog my truck and it's showing code 4 (check engine light).
WATER TEMPERATURE SENSOR SIGNAL--OPEN OR SHORT IN WATER TEMP. SENSOR SIGNAL
--WATER TEMPERATURE SENSOR CIRCUIT
--WATER TEMPERATURE SENSOR
--ECU
I replaced the temp sensor but that doesn't appear to be what the code calls for. Has anyone else had this code? How do i test the temp sensor? It it constant current or does it only recieve current when warm??? Help...
Thanks
