Faulty engine oil pressure
gage.
Faulty dashboard cable
assembly.
Faulty engine control
cable assembly.
Faulty oil pressure
transducer.
If 22 to 26 ohms
resistance is present,
engine oil pressure gage
is faulty.
Circuit breaker OK.
Engine oil pressure gage

Engine oil pressure
gage OK.
POSSIBLE PROBLEMS
Faulty dashboard cable
assembly.
Faulty engine control
cable assembly.
Faulty oil pressure
transducer.
Is 22 to 26 ohms resistance
present between oil
pressure transducer
connector J32-2 and a
known good ground?
If 22 to 26 ohms
resistance is not present,
wire 36 is faulty. If 22 to
26 ohms resistance is
present, oil pressure
transducer is faulty.
Go to step 3 of this fault.
Replace engine oil pressure
gage (para 7-14).
Go to step 4 of this fault.
Replace oil pressure
transducer (para 7-41).
