OIL / FUEL PRESSURE TROUBLESHOOTING GUIDE
1. Check that wires are correctly installed according to the harness
wiring instructions and have not broken, shorted or come loose.
2. Measure continuity (ohms) of each wire from transducer
connector pin to appropriate harness connector pin. There should
be very low resistance if the wire is intact. If resistance is greater
that 0.7 ohms, then stop and correct connections.
3. The following measurements are made by CAREFULLY
unscrewing the transducer connector hood and sliding it back
away from the transducer connector plug (leave the plug in the
transducer). With instrument power ON, perform the following
DC voltage tests at the transducer connector plug. If any test
fails, stop and contact the factory:
