13 |
Oxygen sensor voltage stays between 0.35 and 0.55 volts for 30
seconds with a throttle angle above 4% after engine had been running for at least 40
seconds. |
14 |
Coolant temperature sensor signal indicates a temperature of over
284° F for 4 seconds after engine had been running for 10 seconds. |
15 |
Coolant temperature sensor signal indicates a temperature colder
than -38° F for 4 seconds with the l engine running. |
16 |
ECM sees a battery voltage above 16 volts for more than 10 seconds. |
21 |
TPS voltage was above 1.95 volts for 5 seconds when the MAP sensor
signal showed a high manifold vacuum or the TPS was above 4.9 volts at any time. |
22 |
TPS voltage was under 0.24 volts for 4 seconds when ignition was on. |
24 |
Vehicle speed sensor signal showed less than 3 MPH for 40 seconds
with engine running and transmission in high gear. |
26 |
Quad-driver sense voltage shows a low voltage when battery voltage
should be present or if the sense voltage shows battery voltage when a low voltage should
be present. |
27 |
3rd gear switch was closed or grounded for 10 seconds when vehicle
was in 3rd gear, or drive gear was open when engine was first started. |
28 |
3rd gear switch was closed or grounded for 10 seconds when vehicle
was in 3rd gear, or drive gear was open when the engine was first started. |
29 |
4th gear switch was closed or grounded for 10 seconds when vehicle
was in 4th gear, or drive gear was open when the engine was first started. |
31 |
Park/Neutral switch was open for 4 consecutive starts, or
Park/Neutral switch was grounded with transmission in high gear and vehicle speed was
above 45 MPH for 12 seconds. |
34 |
MAF sensor did not give any signal for 4 seconds when engine was
running. |
38 |
Brake switch signal was not present when vehicle speed changed from
above 35 MPH to 0 MPH 23 or more times. |
39 |
TCC was commanded by the ECM when transaxle was in high gear for 15
seconds but engine speed did not indicate that the TCC was engaged. |
42 |
The EST signal did not change when the ECM applied bypass voltage to
the ignition module. |
43 |
Knock sensor voltage was either above 3.5 volts or below 1.5 volts
for 20 seconds. |
44 |
Oxygen sensor voltage was under 0.25 volts for 4 1/2 minutes of
closed loop operation. |
45 |
Oxygen sensor voltage was over 0.75 volts for 2 minutes of closed
loop operation after engine had been running for at least 1 minute. |
46 |
Power steering switch was closed while vehicle speed was over 40 MPH
for more than 25 seconds. |
48 |
Vehicle misfired. TPS was between 0.58 and 0.93 volts, engine RPM
was between 1500 and 2500 and vehicle speed was between 50 and 60 MPH for 30 seconds. |
66 |
A/C pressure sensor voltage was either above 4.9 volts or below 0.1
volt for 25 seconds. |
