Signal Too High. Intermittent Fault

Signal too high. Intermittent fault

EFI-411 Throttle position (TP) sensor signal

Checking power cable








- Ignition off.
- Disconnect throttle position (TP) sensor.
- Ignition on.
Connect a voltmeter between throttle position (TP) sensor connector terminal 2 and ground.









The voltmeter should read approximately 5 V.

OK - Checking cables and terminals

Not OK - Check cable between throttle position (TP) sensor terminal 2 and engine control module (ECM) #A15 for a short-circuit to supply voltage according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.

Information

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).
