Oxygen sensor voltage stays between 0.35 and 0.55 volts for 30 seconds
after engine had been running for at least 40 seconds. |
| 14 |
Coolant temperature sensor signal indicates a temperature of over
285° F after engine had been running for at least 2 minutes, or if coolant
temperature sensor was shorted to ground. |
| 15 |
Coolant temperature sensor signal indicates a temperature colder than
-38° F for 60 seconds. |
| 16 |
ECM did not receive 2X pulses while receiving 1X pulses. |
| 19 |
7X reference signal problem. ECM has detected either too many or too
few pulses between sync signal within 4 minutes. |
| 21 |
TPS voltage was above 4.0 volts for 5 seconds when the MAP sensor
signal showed manifold vacuum to be 15 pounds or more, or the TPS voltage
was greater than 4.7 volts with throttle closed. |
| 22 |
TPS voltage was under 0.2 volts for 5 seconds when the engine was
running. |
| 23 |
Inlet air temperature sensor signal showed an air temperature of -29°
F after the engine has been running for 5 minutes and 20 seconds. |
| 24 |
Vehicle was not in park or neutral for 20 seconds when throttle position
signal was over 7% with engine speed between 1600 and 3600 RPM and the
MAP signal showed low manifold vacuum. |
| 25 |
Inlet air temperature sensor signal showed an air temperature over
318° F with a vehicle speed greater than 15 MPH. |
| 26 |
Quad-driver sense voltage shows a low voltage for 5 seconds when battery
voltage should be present or if the sense voltage shows battery voltage
for 20 seconds when a low voltage should be present. |
| 33 |
MAP sensor signal voltage was too high (low vacuum) for 5 seconds
when throttle opening was under 12%. |
| 34 |
MAP sensor signal voltage was too low (high vacuum) for 0.2 seconds
when engine speed was under 1200 RPM or when throttle opening was over
15.2%. |
| 35 |
Idle speed was over 175 RPM outside the desired engine speed commanded
by the ECM for at least 5 seconds. |
| 41 |
ECM had received 8-2X reference pulses without receiving any 1X reference
pulses. |
| 42 |
The EST circuit had an open or a ground and the signal did not change
when the ECM applied bypass voltage to the ignition module. |
| 43 |
The ECM did not detect a knock signal during near wide open throttle,
or the knock signal was present for 3.67 seconds or more during normal
engine operation. |
| 44 |
Oxygen sensor voltage was under 0.3 volts for 50 seconds of closed
loop operation. |
| 45 |
Oxygen sensor voltage was over 0.75 volts for 50 seconds of closed
loop operation. |
| 51 |
EPROM error. |
| 53 |
ECM sees a battery voltage of more than 17.1 volts for 0.2 seconds
with ignition on. |
| 62 |
Vehicle speed was less than 5 MPH when vehicle was in 2nd or 3rd gear,
or vehicle speed was greater than 50 MPH when vehicle was in 1st or
2nd gear. |
| 65 |
Fuel injector driver current did not reach 4 amps, injectors commanded
"ON" longer than the calibrated pulse width and battery voltage
was more than 9 volts for 10 seconds. |
