| 13 | Oxygen sensor circuit |
| 14 | Coolant temperature sensor voltage low |
| 15 | Coolant temperature sensor voltage high |
| 21 | TPS voltage was above 2.5 volts for 10 seconds when the MAP sensor signal showed manifold vacuum to be 15 pounds or more with an engine speed less than 1300 RPM. |
| 22 | TPS voltage was under 0.2 volts for 4 seconds when the engine was running. |
| 24 | Vehicle Speed sensor circuit |
| 33 | MAP sensor signal voltage was too high (low vacuum) for 5 seconds when throttle opening was under 2%. |
| 42 | The EST signal did not change when the ECM applied bypass voltage to the ignition module. |
| 44 | Oxygen sensor lean exhaust indication. |
| 45 | Oxygen sensor rich exhaust indication. |
| 51 | PROM not reading. |
