DTC 213

EAS. Code 2-1-3

2-1-3 Throttle position (TP) signal too high

DTC information


Conditions for DTC






The throttle position TP signal is passed from the TP sensor via the transmission control module TCM. The signal tells the TCM how far the throttle damper has opened. The TCM uses the signal in its control functions, among them controlling gear-shifting and the system pressure. The signal normally varies between approx. 0.5 and approx. 4.2 V. Opening the throttle damper increases the signal voltage. If the TCM registers a signal above 4.8 V, DTC 2-1-3 is set.



Substitution value

Control Module GROUP I:
The transmission control module (TCM) "Emergency mode" program is initiated.

Control Module GROUP II:
The transmission control module (TOM) "Emergency mode I" program is initiated.


Defect cause

- Short circuit to battery voltage in the signal wiring.
- Fault throttle position sensor circuit.


Fault symptom

- Rough gear shifting due to maximum system pressure in the transmission
- No Lock-Up operational.
- Gear-shifting operation can change - irregular shifting.
- Fault-tracing starts with EAS1.


EAS1

Other DTCs.






- Read off other DTCs in the engine control module ECM (MFI Fenix 5.2, LH 3.2 or Motronic 4.3).

If DTC 2-4-3 for Fenix 5.2, 4-1-1 for LH 3.2 or 4-1-1 for Motronic 4.3 ECM has been stored:
- Fault-tracing procedures as indicated by the DTC for the ECM.






If none of the above DTCs have been stored:
- Checking throttle position TP signal EAS2.



EAS2

Checking the throttle position TP signal






- Ignition OFF
- Connect test box and check ground points as per GB1-GB2 GB. Connecting the Test Box

- TCM connected
- Ignition ON.

Use a voltmeter to measure between #50 (#B20) and #20 (#A20) on the test box.

- Depress the accelerator pedal AP and take a reading.






The voltmeter should read approx. 0.5 V for closed throttle position CTP and approx. 4.2 V at wide open throttle WOT. The voltage should not exceed 4.8 V at WOT.

If reading is OK:
- Intermittent fault. Fault-tracing as per EAS6.

If the voltmeter reads 4.8 V or more:
- Checking voltage drop over signal ground and power ground EAS3.



EAS3

Checking voltage drop over signal ground (SG) and power ground (PG)





- Ignition ON.
- Turn on as many power consuming items as possible. Use a voltmeter to measure between #20 (#A20) and #29 (#A29) on the test box.

The voltmeter should read less than 0.6 V.

If reading is OK:
- Checking voltage drop over signal ground EAS4.

If reading is incorrect:
- Check ground points 31/32 and 31/33, the cables between the ground points and the TCM #A20 and #A29, and the TCM connector for a break in the circuit as per FA2 and contact resistance and oxidation as per FA6. FA. Checking Wiring and Connections

Then continue with: Checking voltage drop over signal ground EAS4.



EAS4

Checking voltage drop over signal ground






- Ignition OFF
- Test box connected
- Connect a test box to the engine control module ECM (MFI Fenix 5.2, LH 3.2, or Motronic 4.3).






- Control modules connected
- Ignition ON.
- Turn on as many power consuming items as possible.

Use a voltmeter to measure between TCM #20 (#A20) and the ECM test box:

- Fenix 5,2 MFI control module: #42 (#A42), signal ground, control module
- LH 3,2 MFI control module: #20 (#A20), signal ground, control module
- Motronic 4,3 MFI control module: #42 (#A42), signal ground, control module

The voltmeter should read less than 0.1 V.

If reading is OK:
- Checking signal wiring for short circuit to battery voltage EAS5.

If reading is incorrect:
- Check ground point 31/33, wiring between the ground point and the TCM and ECM modules for contact resistance and oxidation as per FA6. FA. Checking Wiring and Connections

Then continue with: Checking signal wiring for short circuit to battery voltage EAS5.



EAS5

Checking signal wiring for short circuit to battery voltage

- Ignition OFF

NOTE: Only Motronic 4.3 MFI control module: Wait approx. 150 seconds.






- Disconnect the ECM (Fenix 5.2, LH 3.2/EZ129K or Motronic 4.3) and the test box
- Ignition ON.

Use a voltmeter to measure between #50 (#B20) and #20 (#A20) on the TCM.
The voltmeter should read approx. 0 V.

If reading is OK:
- Check the TP sensor circuit for the ECM installed.

- Fenix 5.2 DTC 2-4-3 TP signal, permanent malfunction
LH 3.2 DTC 4-1-1 TP sensor signal, permanent malfunction, signal too high
- Motronic 4.3 DTC 4-1-1 TP sensor signal, permanent malfunction, signal too high


If reading is incorrect:
- Check the cable between the TCM #B20 and the ECM #B20 for Fenix 5.2, LH 3.2 and Motronic 4.3 for short circuit to supply as per FA4. FA. Checking Wiring and Connections

- On cars with engine management systems type LH 3.2/EZ129K, also check the cable between ECM LH 3.2 #B20 and EZ129k #B20 for short circuits to supply as per FA4. FA. Checking Wiring and Connections



EAS6

Intermittent Fault.

Checking wiring and connections






- Check the cable between the TCM #820 and the ECM #B20 for Fenix 5.2, LH 3.2 and Motronic 4.3 for intermittent short circuit to supply as per FA4. FA. Checking Wiring and Connections

- On cars with engine management systems type LH 3.2/EZ129k, also check the cable between ECM LH 3.2 #B20 and EZ129K #B20 for intermittent short circuits to supply as per FA4. FA. Checking Wiring and Connections

- Check the TP sensor circuit for the ECM installed.

Fenix 5.2 DTC 2-4-3 TP signal, permanent malfunction
