Mandatory conditions for carrying out "learning" throttle actuator:
- no fault codes P0101, P0102, P0103, P0107, P0108, P0111, P0112, P0113, P0506, and P0507.
- engine speed is in the range of 450-4000 rpm.
- the air pressure in the intake manifold is above 5 kPa.
- air flow above 2 grams/sec.
- ignition voltage "1" more than 10 volts.
Caution: Do not perform this procedure if DTCs are set.
1. Run the engine at idle for three minutes (automatic transmission selector in position "R").
2. Using a scanner, determine the actual crankshaft speed.
3. The ECM will begin learning the new throttle position, after which the RPM will begin to decrease.
4. Turn off the ignition for 60 seconds.
5. Run the engine to idle for three minutes.
6. After three minutes, idling will be normal.
Attention: during "learning" the check engine light may come on (MIL) and a fault code will be recorded. If this happens, clear the codes to ensure the process can continue. If throttle actuator learning has not been done, decelerate to idle speed several times.
7. After the drive cycle, the engine should be running at normal idle speed. If this does not happen, turn off the ignition for 60 seconds and repeat the operations of point 6.
8. At the end of the learning procedure, erase the trouble codes.
