Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-9190

Condition





Turbo engines and 6-cyl non-turbo engines
If Electronic throttle module (ETM) registers that an unreasonably high or low current passes through the electronic throttle module's torque motor, that an incorrect status feedback from the torque motor's drive circuits is sent, or that the throttle disc does not move despite a control signal to the motor, then this information is sent to Engine control module (ECM), which then stores diagnostic trouble code ECM-9190, Faulty current.

5-cyl. non-turbo engines
If Electronic throttle module (ETM) registers that an unreasonably high or low current passes through the electronic throttle module's torque motor or an incorrect status feedback from the torque motor's drive circuits is sent, then this information is sent to Engine control module (ECM), which then stores diagnostic trouble code ECM-9190, Faulty current.

Substitute value

Fuel cut-off that follows accelerator pedal position.
Engine speed is regulated via fuel cut-off by deactivating the injectors one at a time. Engine speed is determined by gas pedal position sensor position and engine speed is maximized to about 5000 rpm. This reconfiguration can cause the engine to idle very unevenly since the engine control module (ECM) regulates engine speed by cutting of the fuel to the cylinders individually. Do not confuse this reconfiguration (engine behavior) with an actual driveability problem that was present before reconfiguration.

Closing of throttle during braking.
The accelerator pedal position is ignored when the brake pedal is depressed.

Throttle closed.
The electronic throttle module (ETC.) deactivates the throttle motor control, which means that the throttle is not actuated and assumes its mechanical stop position. This means about 20% throttle opening. This reconfiguration is always followed by fuel cut-off.

Cruise control off.
Cruise control off during entire operating cycle in which fault was detected. If the fault is no longer present, the function is available the next time the car is started.
For upgraded software, released in 2006 or later, adjustments have been made to substitute values. In the driving cycles when the problem is active, fuel shut-off will follow the accelerator pedal position; cruise control and throttle will be shut off.

Possible source
- the power supply to the throttle unit
- poorly charged battery or corroded in the connecting cables
- defective throttle unit.
- This diagnostic trouble code is generated in combination with other trouble codes. Information on the possible root cause is described.

Fault symptom[s]
- the accelerator pedal (AP) is ignored when braking
- the cruise control cannot be activated
- uneven idle
- jerks during engine braking
- very poor accelerator response
- maximum speed approximately 50 km/h
- the ETS warning lamp lights (C70 and S/V70 -2000 only).
