1994 2.2L Fuel Injection, VIN 4 |
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. |
