Signal Missing - Intermittent Fault

Signal missing. Intermittent fault

Checking connectors and wiring
Check the engine speed (RPM) sensor connector. Check for intermittent contact resistance and oxidation.
Check the signal cable between the engine speed (RPM) sensor terminal #1 and engine control module (ECM) terminal #A48 (#A48) and between the engine speed (RPM) sensor terminal #2 and engine control module (ECM) terminal #A66 (#B6). Check for an intermittent short-circuit to supply voltage. Check for an intermittent short-circuit to ground. Check for an intermittent open-circuit.
Check the carrier plate, search for damage and other defects.
Remedy as necessary

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).
