Condition




The throttle position (TP) sensor signal comes from the throttle position (TP) sensor on the throttle body (TB) via the engine control module (ECM). This signal indicates to the transmission control module (TCM) how far the throttle has opened. The transmission control module (TCM) uses the signal to control functions such as gear-shifting and system pressure. The signal normally varies between approx. 0.5 and approx. 4.2 V. Opening the throttle increases the signal voltage. Diagnostic trouble code (DTC)AT-213 is posted if the transmission control module (TCM) registers a signal above 5.2 V for approx. 10 seconds.

Substitute value
The transmission control module (TCM) "Emergency mode I" program has been initiated.

Possible source
- Short-circuit to supply voltage in the signal cable.
- Fault in throttle position (TP) sensor circuit.

Fault symptom[s]
- The combined instrument panel warning lamp flashes.
- No lock-up function.
- No adaption of the gear slippage times at high altitude (High Altitude Compensation)
- Gear-shifting can change - irregular shifting.

Note! The Motronic 4.4 engine control module (ECM) posts a diagnostic trouble code (DTC) when the transmission sends a malfunction indicator lamp (MIL) request. Erase this diagnostic trouble code (DTC) in the Motronic engine control module (ECM) when the fault in
