| 13 | Oxygen sensor voltage stays between 0.35 and 0.55 volts for 30 seconds
when the TPS signal was above 0.55 volts. The engine had been running for
at least 40 seconds with an engine temperature above 110° F. |
| 14 | Coolant temperature sensor signal indicates a temperature of over 284°
F for 0.4 seconds after the engine had been running for at least 10 seconds. |
| 15 | Coolant temperature sensor signal indicates a temperature colder than
-36° F for at least 4 seconds after the engine had been running for 2 seconds. |
| 16 | Charging system voltage was above 16 volts for 10 seconds. |
| 21 | TPS voltage was above 0.8 volts for 5 seconds when engine was running
and air flow was less than 15 gm/sec, or the TPS voltage was over 4.8 volts
at any time. |
| 22 | TPS voltage was under 0.2 volts for 4 seconds when the ignition was on.
On Bonneville, Le Sabre and Park Avenue the TPS voltage was between 0.48
and 1.3 volts for 30 seconds with engine speed between 1300 and 2100 RPM
and vehicle speed between 50 and 60 MPH. |
| 23 | Inlet air temperature sensor signal showed an air temperature of -40°
F for 0.4 seconds (On Regal the temperature was -31° F). |
| 24 | Vehicle speed sensor signal showed less than 3 MPH for 2 seconds when
engine speed was greater than 3000 RPM and transmission has not been in
park or neutral for more than 4 seconds. Or vehicle speed goes from above
18 MPH to 0 in less than 2 seconds without applying brake. |
| 25 | Inlet air temperature sensor signal showed an air temperature of over
218° F for 5 seconds when vehicle speed was greater than 35 MPH. |
| 26 | Quad-Driver sense voltage shows a low voltage when battery voltage should
be present, or if the sense voltage shows battery voltage when a low voltage
should be present for at least 5 seconds when the engine was running. |
| 27 | 2nd gear switch was closed or grounded for 10 seconds when vehicle was
in 4th gear, or 2nd or 4th, gear switch was open when engine was first started. |
| 28 | 3rd gear switch was closed or grounded for 10 seconds when vehicle was
in 4th gear, or 3rd or 4th, gear switch was open when engine was first started. |
| 29 | 4th gear switch was closed or grounded for 10 seconds when vehicle was
in 4th gear, or 4th gear switch was open when engine was first started. |
| 31 | PRNDL indicates a gear other than park or neutral for 13 seconds for 3
consecutive startups when ignition was on, engine was off and vehicle speed
was 0. Or the PRNDL status indicators (A, B, C, P) showed an incorrect combination
of Lo and Hi for more than 10 seconds. |
| 34 | There was no MAF signal for over 4 seconds while engine was running. |
| 38 | Vehicle went from 35 MPH (for 10 seconds) to 0 MPH 5 times without a TCC
brake input signal. |
| 39 | The Torque Converter Clutch portion of the brake switch was inoperative
for 30 seconds causing vehicle speed ratio to be outside of its window of
operation. |
| 41 | Cam sensor signal was not received by PCM for the last 2 seconds while
engine was running. |
| 42 | The EST signal did not change when the ECM applied bypass voltage to the
ignition module. |
| 43 | Knock sensor signal was either above 3.5 volts or below 1.5 volts for
at least 20 seconds. |
| 44 | Oxygen sensor voltage was under 0.25 volts for up to 4 1/2 minutes of
closed loop operation. |
| 45 | Oxygen sensor voltage was over 0.750 volts for 2 minutes in closed loop
operation with a throttle angle between 0.6 and 1.9 volts. |
| 51 | MEM-CAL error. |
| 63 | EGR flow was incorrect. |
| 64 | EGR flow was incorrect. |
| 65 | EGR flow was incorrect. |
