Diagnostic trouble code (DTC) information

Condition
Diagnostic trouble code (DTC) ECM-70 is stored if the control module registers that the throttle position sensor signal cable between the engine control module (ECM) and the DSA control module has a short-circuit to ground / voltage or if there is an open-circuit in the circuit.

Substitute value
DSA function disabled.

Possible source

Signal too high:
- Short-circuit to supply voltage in the signal cable.

Signal too low:
- Contact resistance in the terminals
- Short-circuit to ground in the signal cable.

Signal missing:
- Contact resistance in the terminals
- Open-circuit in the signal cable.

Fault symptom[s]
- DSA-lamp lights
- No DSA function.
