DTC Detection Condition

Trouble Area

P0222

Output voltage of VTA2 1.75 V or less for 2 seconds (1 trip detection logic)

• Throttle position (TP) sensor (built into throttle body)

• Short in VTA2 circuit

• ECM

P0223

Output voltage of VTA2 4.8 V or more when VTA1 between 0.2 V and 2.02 V (1 trip detection logic)

• Throttle position sensor (built into throttle body)

• Open in VTA2 circuit

Short between VC and VTA2 circuit

• ECM

P2135

Either condition (a) or (b) met (1 trip detection logic):

(a) Difference between output voltages of VTA1 and VTA2 0.02 V or less for 0.5 seconds or more

(b) Output voltage of VTA1 0.2 V or less, and VTA2 1.75 V or less, for 0.4 seconds or more

• Short between VTA1 and VTA2 circuit

• Throttle position sensor (built into throttle body)

• When any of these DTCs are set, check the throttle valve opening angle by selecting the following menu items on an intelligent tester: DIAGNOSIS / ENHANCED OBD II / DATA LIST / ETCS / THROTTLE POS AND THROTTLE POS #2.

• THROTTLE POS denotes the VTA1 signal (expressed in percentages), and THROTTLE POS #2 denotes the VTA2 signal (expressed in voltages).
