P1692 — Electronic throttle control monitor level 2/3 - motorised throttle control and fuel injection switch off A

Diagnostic algorithm

1. Connect a full-function scan tool, read and record all DTCs and freeze-frame data. Note any associated codes (pedal, supply, communication).
2. Check battery voltage and charging at key ON and cranking. Recharge or replace battery if low. Test with known-good battery if intermittent low-voltage suspected.
3. Visually inspect harnesses and connectors at throttle body and accelerator pedal module for damage, corrosion, water entry or loose pins. Repair or clean as needed.
4. With a DVOM or scope, monitor accelerator pedal sensor 1 and 2 voltages while operating pedal; verify signals are within expected ranges and correlate to each other and to pedal travel.
5. Command a throttle actuator/self-test using the diagnostic tool (actuator test). Observe throttle response, reported angle, and any fault return. Do not force the throttle mechanically while performing tests.
6. Measure throttle actuator supply and ground during a commanded movement. Look for proper supply voltage and pulsed control signals from the DME. Check actuator motor current for excessive draw or open circuit.
7. Check for CAN/LIN communication errors and verify all related modules are communicating; repair network faults first.
8. Inspect throttle plate mechanically for binding or heavy carbon; clean only if access and procedure are manufacturer-approved.
9. If wiring and actuator check out, consider reflashing or updating DME software per latest technical bulletins. Follow manufacturer procedures for throttle adaptation/calibration.
10. If tests indicate actuator or pedal sensor failure, replace the faulty component and clear codes. Relearn/adapt throttle as required and verify normal operation over multiple key cycles and road test.
11. If fault persists after component replacement and wiring verified, investigate DME internal driver or replace DME as last resort (after confirmation with manufacturer diagnostics).
