1998 Chevrolet Tahoe Repair Question
Mileage: 208,413 miles.
What do i need to check or replace?
ive also noticed a coolant leak by the throttle body but i cant see where exactly its coming from
Answer
what was the code number?? did anyone check for a vacuum leak??
Roy
P0117 and everyone who usually helps is outta town so no one has checked for a vacuum leak.
117 is a coolant sensor code. could be wiring , sensor, thermostat.
you need a shop with a scan tool to monitor the sensor voltage when it is cold and hot to see the actual readings.

Ive changed the coolant temperture sensor and the thermostat. could coolant system be my problem rather than anything to do with the fuel system?
or am i trying to rule the coolant system out?
did it get tested before the replacement or did you just throw the part at it?? you need freeze frame data to see the readings when the failure occurred. as you see, the sensor did not cure the issue and further diag time is required to find the fault.
