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.
