codes, a mechanically sprung 7% opening may be applied.
Throttle Position Sensor 'A'/'B' Voltage Correlation
P2135 Throttle position sensor ‘A/B’ voltage correlation
Description
Two potentiometers are built into the throttle actuator unit in order to provide a throttle position signal to the
ECU. Two processors within the ECU compare the two output signals, which should match within a defined
tolerance. Note that the potentiometers operate on 5 volts.
Enable Criteria:
• None
Disable Criteria:
• Throttlepositiongreaterthan60%
Potential failure modes:
• TPS1readingincorrectly
• TPS2readingincorrectly
Notes: A maximum throttle opening of 15% may be imposed.
