2. Monitor the "TPS VOLTAGE 1" and "TPS VOLTAGE 2" parameters on the Scantool data list.
A. Specification: Refer to "Signal Waveform & Data" in the "General Information" procedure
- Output of TPS 1 increases smoothly in proportion with the throttle valve opening angle.
- Output of TPS 2 decreases smoothly in inverse proportion with the throttle valve opening angle.
3. Are the TPS VOLTAGE 1 & 2 within the specification ?
YES
1) Go to W/Harness Inspection
NO
1) Check TPS 1 & 2, referring troubleshooting guide for DTC P0121/P0221. Repair or replace as necessary and go to "Verification of Vehicle Repair" procedure
