: DTC P0222; THROTTLE POSITION (TP) SENSOR CIRCUIT TP2 HIGH/LOW VOLTAGE

G258127t14 : CHECK TP SENSOR SENSING CIRCUIT TP2 FOR HIGH RESISTANCE
1. Disconnect the battery negative terminal.
2. Disconnect the TP sensor electrical connector, PI26.
3. Disconnect the ECM electrical connector, PI01.
4. Measure the resistance between PI01, pin 76 (Y) and PI26, pin 02 (Y).

- Is the resistance greater than 5 ohms?

-> Yes
REPAIR the high resistance circuit. CLEAR the DTC. TEST the system for normal operation.

-> No

G258127t15 : CHECK TP SENSOR SENSING CIRCUIT TP2 FOR SHORT TO HIGH VOLTAGE
1. Reconnect the battery negative terminal.
2. Turn the ignition switch to the ON position.
3. Measure the voltage between PI26, pin 02 (Y) and GROUND.

- Is the voltage greater than 5 volts?

-> Yes
REPAIR the short circuit to high voltage. CLEAR the DTC. TEST the system for normal operation.

-> No

G258127t16 : CHECK TP SENSOR SENSING CIRCUIT TP2 FOR SHORT TO GROUND
1. Measure the resistance between PI26, pin 02 (Y) and GROUND.

- Is the resistance less than 10,000 ohms?

-> Yes
REPAIR the short circuit to GROUND. CLEAR the DTC. TEST the system for normal operation.

-> No
INSTALL a new TP sensor. CLEAR the DTC. TEST the system for normal operation.
