| 13 |
Oxygen sensor voltage stays between 0.35 and 0.55 volts for 20 seconds.
Engine was at normal operating temperature and had been running for at least
2 minutes after start with a throttle angle above 6%. |
| 14 |
Coolant temperature sensor signal indicates a temperature above 285° F
after the engine has been running for at least 2 minutes. |
| 15 |
Coolant temperature sensor signal indicates a temperature colder than
-38° F after the engine has been running for at least 1 minute. |
| 21 |
TPS voltage was above 3.9 volts for 5 seconds when the MAP sensor signal
showed manifold vacuum to be 15 pounds or more and engine speed was less
than 1750 RPM or TPS voltage was below 1.9 volts for 64 seconds. |
| 22 |
TPS voltage was under 0.21 volts for 5 seconds when the engine was running. |
| 23 |
Inlet air temperature sensor signal showed an air temperature below -30°
F or above 302° F for more than 2 seconds after the engine has been running
for 2 minutes. |
| 24 |
When engine speed was between 1700 and 3600 RPM and throttle position
angle was less than 1%, the MAP signal showed low voltage (high manifold
vacuum) for at least 5 seconds. |
| 25 |
Inlet Air Temperature Sensor signal showed an air temperature over 304°
F after the engine has been running for 5 minutes and 20 seconds and the
vehicle speed was greater than 15 MPH. |
| 26 |
Quad-Driver sense voltage shows a low voltage when battery should be present
or the sense voltage shows battery voltage when a low voltage should be
present for at least 20 seconds. |
| 27 |
Quad-Driver sense voltage shows a low voltage when battery should be present
or the sense voltage shows battery voltage when a low voltage should be
present for at least 20 seconds. |
| 28 |
Quad-Driver sense voltage shows a low voltage when battery should be present
or the sense voltage shows battery voltage when a low voltage should be
present for at least 20 seconds. |
| 32 |
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. |
| 33 |
MAP sensor signal voltage was too high for 10 seconds when throttle opening
was under 12%. |
| 43 |
The ECM did not detect a knock signal during near wide open throttle operation,
or the knock signal was present for 3.5 seconds or more during normal engine
operation. |
| 44 |
Oxygen sensor voltage was under 0.3 volts for 50 seconds of closed loop
operation. Throttle angle was above 5%. |
| 51 |
EPROM error. |
| 53 |
Battery voltage was higher than 17.1 volts for 0.2 seconds, or below 10
volts for 4 minutes. |
| 55 |
Oxygen sensor voltage was less than 0.3 volts for 5 seconds of closed
loop operation. |
| 66 |
A/C refrigerant pressure voltage was either less than 0.19 volts or greater
than 4.9 volts for 15 seconds, or the pressure voltage was above 4.0 volts
when A/C clutch was not requested. |
