13 |
Oxygen sensor voltage stays between 0.35 and 0.55 volts for 30
seconds when the TPS signal was above 3%. The engine had been running for at least 2
minutes. |
14 |
Coolant temperature sensor signal indicates a temperature of over
275° F after the engine had been running for at least 10 seconds. |
15 |
Coolant temperature sensor signal indicates a temperature colder
than -38° F for at least 2 seconds. |
16 |
Charging system voltage was below 8 volts for 5 seconds while engine
speed was more than 1000 RPM. |
17 |
PCM did not detect any cam reference pulses for 3 seconds while
engine was running. |
21 |
TPS voltage was above 3.8 volts for 5 seconds with engine speed over
600 RPM and throttle steady. |
22 |
TPS voltage was under 0.2 volts for 3 seconds when the ignition was
on. |
23 |
Inlet air temperature sensor signal showed an air temperature of
-31° F for 4 minutes. |
24 |
Engine speed was greater than 3000 RPM but vehicle speed was less
than 5 MPH for 4 seconds with brake not applied. |
25 |
Inlet air temperature sensor signal showed an air temperature of
over 297° F for 5 seconds when vehicle speed was greater than 1 MPH. |
28 |
The PCM received a wrong combination of High and Low pulses from the
transaxle range switch for more than 10 seconds. |
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 3 seconds when engine speed was
over 500 RPM and throttle angle was above 3%. |
35 |
Engine idle speed is either 300 RPM above or below the desired idle
speed for 50 seconds. |
36 |
PCM did not receive 6 or more 24X (crank reference) pulses per
ignition cycle. |
37 |
TCC brake switch signal was not received by PCM when the vehicle
speed went from 35 MPH or above (for 10 seconds) and back to 0, four consecutive times. |
41 |
Cam sensor signal was not received for 5 seconds while engine was
running. |
43 |
Knock sensor signal was either above 4.6 volts or below 0.84 volts
for at least 10 seconds. |
44 |
Oxygen sensor voltage was under 0.25 volts for at least 60 seconds
of closed loop operation. |
45 |
Oxygen sensor voltage was over 0.75 volts for 60 seconds in closed
loop operation with a throttle angle between 6% and 20%. |
51 |
MEM-CAL error. |
52 |
CALPAK error. |
53 |
ECM sees a battery voltage of more than 16.9 volts when engine speed
was above 800 RPM. |
54 |
Fuel pump voltage was less than 7 volts or more than 14 volts for 3
seconds. |
72 |
Speed sensor signal changed more than 45 MPH in 2 seconds when
vehicle was not in park or neutral. |
75 |
TPS was at 0% but engine speed was between 1400 and 2000 RPM for
three consecutive times. |
76 |
TPS was at 0% but engine speed was between 1400 and 2000 RPM for
three consecutive times. |
77 |
TPS was at 0% but engine speed was between 1400 and 2000 RPM for
three consecutive times. |
82 |
PCM did not detect any 3X reference pulses during cranking of
engine. |
90 |
TCC did not unlock when commanded to OFF. Torque converter clutch
slip was between 10 and 40 RPM (full lock would be 0 RPM) for 10 seconds. Throttle angle
was over 30% with normal transmission fluid temperature and gear selector in D3 or D4. |
