Demand 0% for 5 secs and 100% for 5 secs to see whether throttle feedback is matching the throttle demand (a little delay is accepted). If it is not matching, there is still issue with throttle valve - Step 7 If the problem persists, replace the intake throttle - Associated Parameters: Parameter Label Description DID Monitoring Throttle desired position Demanded Throttle position FEA6 Both should match with error less than 2% Throttle Feedback position Throttle Feedback position FEA8 First close position counts learnt THRTL First learnt throttle close position counts FEA9 Ranges from 80 to 150 First open position counts learnt THRTL First learnt throttle open position counts FEAA Ranges from 750 to 850 Current Throttle close position counts learnt Current Throttle close position counts learnt FEAB Ranges from 80 to 150 Current Throttle open position counts learnt Current Throttle open position counts learnt FEAC Ranges from 750 to 850 Verification condition: Warm up the engine above 80degC and do key off till power latch twice to confirm whether the fault is cleared.
