Scania COO DTC 4096 Throttle control sensor

COO Coordinator · Scania

Code 4096 (decimal). Some diagnostic tools show it in hexadecimal as 1000.

In short

The voltage in the throttle control sensor circuit has either been above or below the permitted level. The fault code is generated: - if the supply voltage to the sensor has fallen below 4.1 V or exceeded 6.1 V - if the signal voltage from the sensor has fallen below approx. 0.25 V or exceeded approx. 4 V

Applies to: COO4 IMCOO4 IM (Slave)

What does Scania COO fault code 4096 mean?

The voltage in the throttle control sensor circuit has either been above or below the permitted level. The fault code is generated: - if the supply voltage to the sensor has fallen below 4.1 V or exceeded 6.1 V - if the signal voltage from the sensor has fallen below approx. 0.25 V or exceeded approx. 4 V

What causes Scania DTC 4096?

Short circuit or open circuit in the throttle control sensor circuit. There may also be an internal fault in the throttle control sensor or in exceptional cases in the coordinator.

How does the system react?

The engine will not respond to throttle actuation as long as the fault is active.

How to fix Scania COO fault code 4096?

  1. Check the throttle control sensor wiring and connector.
  2. Measure between coordinator pin 28 and pin 24 to check the supply voltage.
  3. Measure between coordinator pin 54 and pin 24 to check the signal voltage.
  4. Check whether the engine control unit also has set any fault codes.
  5. If this is shown to be an internal fault in the coordinator, the coordinator must be renewed.
