Throttle position sensor troubleshooting
Hi all,
My truck will not idle. Trouble codes show possible TPS problems. I checked base voltage to TPS connector and it read 4.96 volts. I then backprobed wires at the sensor and they read the same (4.96) no matter where I moved the throttle (closed, halfway, open). Am I checking the TPS correctly?
Perhaps I'm doing it wrong!? Any help would be appreciated! Thanks in advance.
