1992 2.2L Fuel Injection, VIN 4 |
13 |
Oxygen sensor voltage stays between 0.35 and 0.55 volts for 40
seconds. Engine was at normal operating temperature and had been running for at least 2
minutes after start with a throttle angle above 5%. |
14 |
Coolant temperature sensor signal indicates a temperature below
-30° F or above 275° F for 3 seconds after the engine has been running for 2 minutes. |
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. |
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 1400 and 3600 RPM and the MAP signal
showed low voltage (high manifold vacuum) for at least 5 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 higher than 3.7 volts for 5 seconds
when throttle opening was under 5%, or MAP sensor signal was lower than 0.3 volts when
throttle opening was over 15%. |
42 |
The EST signal did not change when the ECM applied bypass voltage to
the ignition module. |
44 |
Oxygen sensor voltage was under 0.27 volts for 25 seconds of closed
loop operation. |
45 |
Oxygen sensor voltage was over 0.7 volts for at least 50 seconds of
closed loop operation. |
51 |
ECM error. Check that all ECM connections are good and recheck ECM.
If code 51 still exists then replace ECM. |
66 |
A/C refrigerant pressure voltage was either less than 0.3 volts or
greater than 4.9 volts for 5 seconds. |
