DTC7 Engine Speed Signal Open Circuit or Short
Circuit Description
PCM (Powertrain Control Module) converts signals from
the crankshaft position sensor into the engine speed
signals (pulse) and sends these to the control unit and
tachometer.
Diagnostic Aids

Inspect the wiring for poor electrical connections at
the control unit connector. Look for possible bent,
backed out, deformed, or damaged terminals. Check
for weak terminal tension as well.
Also check for a chafed wire that could short to bare
metal or other wiring. Inspect for a broken wire inside
the insulation.

When diagnosing for a possible intermittent short or
open condition, move the wiring harness while
observing test equipment for a change.

Check harness routing for a potential short to ground
in circuit BLK/RED.
