1. Monitor the 5v reference, Gray wire to the Throttle Position Sensor
(TPS) with a Digital Volt Ohm Meter (DVOM) set to the MIN/MAX setting.
2. Monitor the TPS signal circuit, Blue wire with a DVOM. Voltage
should range smoothly from approximately 0.44 to 5.0 volts as the
throttle is opened.
3. Tap test the Electronic Control Module (ECM) and see if the codes come back or if the engine reacts.
possible causes wiring or Powertrain Control Module (PCM)
