| 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. |
