DH16 - Check TP Sensor Signal Versus Engine Load While Driving

- Key On, Engine Running.

- Do normal drive, exercising the throttle and TP sensor near higher gears (preferably overdrive) while accessing PIDs.

- Access TP PID and LOAD PID with the Scan Tool and record readings.

- Is the TP PID reading less than 4.90% (0.24 volts) and the LOAD PID reading greater than 60%?

YES -- CHECK if the TP sensor is loosely connected to the throttle body (screws not securely tightened down). SERVICE as necessary. COMPLETE PCM reset to clear DTCs. DRIVE vehicle exercising the throttle. Rerun quick test. Diagnostic Subroutines (DSR) - Extracting Codes

If Continuous Memory 1121 is now present, REPLACE MAF sensor.

NO -- Unable to identify the fault at this time. If vehicle is still a No Start, Go to Pinpoint Test Step A1. A - No Start Test
