Check the engine speed (RPM) sensor connector. Check for intermittent contact resistance and oxidation.

HINT: The engine speed (RPM) sensor and its wiring are sensitive to interference from surrounding cables, the starter motor cable for example, or similar high amperage cables.

Interference can cause difficulty in starting the engine, prevent the engine starting at all, or cause intermittent operation of the tachometer, etc.

Check whether any cables with high power consumption are incorrectly installed, i. e. too close to the engine speed (RPM) sensor or its wiring.

Checking the wiring

Check the signal cable between engine control module (ECM) terminal #A40 and oil level sensor terminal #1. Check for a short-circuit to supply voltage.

HINT: With the ignition on, the voltage between terminals #2 and #3 must be 5 V, with the reading taken at the oil level sensor connector.

Try a new oil level sensor if no fault is found and the fault is permanent.

Remedy as necessary.
