Working on a 2004 5.3. Code 2315. Replaced the sensor on foot pedal. Replaced throttle body and tps sensor. Replaced the plug that goes to the tps. Soldered the wires.
Checked and cleaned all grounds. There’s is 5volts at both wires at the tps and both grounds check good too. Maf sensor probed ok.
Here’s where it gets wierd. Testing the terminals coming out of tps sensor there is no ohms. This is second brand new throttle body and sensor. Neither have ohms. If I probe the old sensor I get ohms. The reduced engine power was intermittent. Now with two new throttle body with new sensors the problem is no longer intermittent. Here’s the link to the tests I performed. What am I missing? Thank you. https://easyautodiagnostics.com/gm/4.8L-5.3L-6.0L/throttle-body-resistance-specs-1
