|93-95 3.4L VIN X
||Oxygen sensor voltage stays between 0.35 and 0.55 volts for 25 seconds.
The engine had been running for at least 2 minutes and the TPS was above
||Coolant temperature sensor signal indicates a temperature of over 270°
F after the engine had been running for 20 seconds.
||Coolant temperature sensor signal indicates a temperature colder than
-37° F when the engine was running.
||TPS voltage was above 3.78 volts for 1.25 seconds.
||TPS voltage was under 0.25 volts for 10 seconds when the engine was running.
||Inlet air temperature sensor signal showed an air temperature of -31°
F for 10 seconds after the engine has been running for 4 minutes.
||Vehicle speed sensor signal showed less than 2 MPH for 3 seconds when
throttle position signal was less than 2% with engine speed between 2200
and 4400 RPM with the vehicle in gear.
||Inlet air temperature sensor signal showed an air temperature of over
293° F and vehicle speed was greater than 1 MPH.
||EGR open command did not change the fuel mixture when the command was
given during off idle operation. EGR opening should cause the mixture to
be slightly richer because of the low oxygen content of exhaust gas.
||MAP sensor signal voltage was too high (low vacuum) for 5 seconds when
throttle opening was under 6%.
||MAP sensor signal voltage was too low (high vacuum) for 22 seconds when
engine speed was under 625 RPM, or when engine speed was over 625 RPM and
throttle opening was over 20% for 22 seconds.
||Idle speed was over 200 RPM outside the desired engine speed commanded
by the ECM for 50 seconds.
||Transaxle clutch switch has failed 4 consecutive times. Vehicle was at
normal operating temperature and the speed went from 0 to 40 MPH or more
and back to 0 again.
||The EST signal did not change when the ECM applied bypass voltage to the
||Knock sensor signal voltage was either above 4.8 volts or below 0.64 volts
for 10 seconds.
||Oxygen sensor voltage was under 0.2 volts for 60 seconds of closed loop
||Oxygen sensor voltage was over 0.7 volts for 50 seconds of closed loop
operation. Engine had been running for at least 1 minute with the throttle
angle between 3% and 45%.
