Throttle Position (TP) Sweep Inspection
WARNING: This page is about a different variant/trim than selected.
- Connect WDS or equivalent to DLC-2.
- Turn ignition on.
- Verify none of the following DTCs are displayed: P0121, P0122, P0123, P0221, P0222, P0223, P2100, P2101, P2102, P2103, P2107, P2108, P2119, P2122, P2123, P2127, P2128, P2135, P2136. If any of these DTC are displayed, perform DTC inspection. Refer to DIAGNOSTIC TROUBLE CODE DEFINITIONS .
- Access TP_REL PID.
- Verify PID reading is within Closed Throttle Position (CTP) value. Refer to PIN VOLTAGE & PID VALUE CHARTS
in PIN VOLTAGE CHARTS article. If PID reading is out of range, perform following:
- Remove air duct from throttle valve body
- Verify throttle valve opens when accelerator pedal is depressed
- Gradually depress accelerator pedal and verify PID reading increases lineally. If PID reading drops momentarily, inspect TP sensor.
- Fully depress accelerator pedal and verify PID reading is within Wide Open Throttle (WOT) value. Refer to PIN VOLTAGE & PID VALUE CHARTS
in PIN VOLTAGE CHARTS article. If the PID reading is out of range, perform the following:
- Remove the air duct from throttle valve body.
- Verify throttle valve opens when accelerator pedal is depressed.
