1989 3.1L Multi Port Fuel Injection, VIN V |
13 |
Oxygen sensor voltage stays between 0.35 and 0.55 volts for 60
seconds when the TPS signal was above 4%. The engine had been running for at least 2
minutes. |
14 |
Coolant temperature sensor signal indicates a temperature of over
275° F for 3 seconds. |
15 |
Coolant temperature sensor signal indicates a temperature colder
than -38° F for at least 20 seconds. |
21 |
TPS voltage was above 4.3 volts for 10 seconds when engine was
running and air flow was less than 17 gm/sec. |
22 |
TPS voltage was under 0.25 volts for 4 seconds when the ignition was
on. |
23 |
Manifold air temperature sensor signal showed an air temperature of
-31° F for 10 seconds after engine had been running for 4 minutes. |
24 |
Engine speed was between 2200 and 4400 RPM and transmission was not
in park or neutral and TPS was less than 2% for 3 seconds. |
25 |
Manifold air temperature sensor signal showed an air temperature
over 293° F for 3 seconds when vehicle speed was greater than 3 MPH and engine had been
running for 8 minutes. |
26 |
Quad-driver sense voltage showed a low voltage when battery voltage
should be present, or the sense voltage showed battery voltage when a low voltage should
be present. |
32 |
The ECM opens each EGR control valve during deceleration and
monitors the change in manifold vacuum. The code is set when the change in manifold vacuum
is outside the normal range. |
33 |
MAP sensor voltage was too high for 4.8 seconds when throttle angle
was less than 2%. |
34 |
MAP sensor voltage was too low for 1 second when engine speed was
under 600 RPM, or MAP sensor voltage was too low for 1 second when engine speed was over
600 RPM and throttle angle was above 20%. |
41 |
Faulty or incorrect MEM-CAL. |
43 |
Knock sensor signal was either above 3.5 volts or below 1.5 volts
for at least 0.5 seconds. |
44 |
Oxygen sensor voltage was under 0.2 volts for at least 60 seconds of
closed loop operation. |
45 |
Oxygen sensor voltage was over 0.7 volts for 50 seconds in closed
loop operation with a throttle angle between 3% and 45%. |
51 |
MEM-CAL error. |
52 |
CALPAK error. |
53 |
ECM sees a battery voltage of more than 17.1 volts for 2 seconds. |
54 |
Fuel pump voltage was less than 4 volts for 0.4 seconds. |
62 |
Vehicle gear commanded by ECM did not match actual gear selected. |
66 |
A/C pressure sensor voltage was either above 4.9 volts or below 0.1
volts for at least 5 seconds. |
