Your engine will use either a mass airflow sensor and burn off circuit OR a manifoldabsolute pressure sensor.2. A PROM, Mem-Cal or Cal-Pak chip that has not been fully seated or that has a bentcontact may cause one or all of these codes to set.3. If the Park/Neutral Indicator switch isn't wired correctly this code can set.4. Early version TPI and TBI systems only.5. Can be caused by a clogged fuel filter or a vacuum leak.6. Can be caused by a clogged air filter.7. Can be caused by a bad fuel pump relay.Table 9.1 Diagnostic Trouble Codes25
