Lotus Service Notes
Throttle Actuator Control Module Performance
Monitor: Continuous
Enable Criteria: Engine running
Disable Criteria: None
Potential failure modes:
# ECU internal failure
# Short circuit to throttle actuator
Pedal Position Sensor 'D' Circuit Low
Description
Two potentiometers are built into the throttle pedal unit in order to provide a throttle demand signal to the ECU.
Note that the potentiometers operate on 5 volts.
Enable Criteria: None
Disable Criteria: None
Potential failure modes:
# Signal short circuit (< 0.283 V)
# Reference voltage open circuit
# Reference voltage short to ground
# Sensor failure
Notes: A maximum throttle opening of 15% may be imposed due to this single code. In the case of multiple
codes, a mechanically sprung 7% opening may be applied.
Pedal Position Sensor 'D' Circuit High
Enable Criteria: None
Disable Criteria: None
Potential failure modes:
# Signal open circuit (> 4.487 V)
# Reference voltage open circuit
# Reference voltage short to ground
# Sensor failure
Notes: A maximum throttle opening of 15% may be imposed due to this single code. In the case of multiple
codes, a mechanically sprung 7% opening may be applied.
