Pedal Position Sensor 'E' Circuit High; Throttle Position Sensor 'A'/'B' Voltage Correlation - Lotus Evora Service Notes

Lotus Service Notes

Pedal Position Sensor 'E' Circuit High

P2128 Pedal position sensor 'E' 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.

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.
