Notice:
Perform the reset memory procedures (a/t initialization) when replacing the automatic transaxle assembly, engine assembly or ecm (see page ax-18).
Hint:
Reset memory cannot be completed by only reconnecting the cable to the negative (-) battery terminal.
Caution:
When using compressed air, always aim away from yourself to prevent automatic transmission fluid (atf) or kerosene from spraying on your face.
Notice:
Clean all components thoroughly to remove all foreign matter.
Clean both sealing surfaces with a non-residue solvent.
Apply fipg material in a continuous line approximately 1 mm (0.04 In.) In diameter on the sealing surface.
Reassemble parts within 10 minutes of applying fipg material. Failing to do so will require the fipg material to be removed and reapplied.
Definition of terms
Term | Definition |
Monitor description | Description of what the ecm monitors and how it detects malfunctions (monitoring purpose and its details). |
Related dtcs | Diagnostic code. |
Typical enabling condition | Preconditions that allow the ecm to detect malfunctions.
With all preconditions satisfied, the ecm sets the dtc when the monitored value(s) exceeds the malfunction threshold(s). |
Sequence of operation | The priority order that is applied to monitoring, if multiple
sensors and components are used to detect the
malfunction.
While another sensor is being monitored, the next sensor or component will not be monitored. |
Required sensor/components | The sensors and components that are used by the ecm to detect malfunctions. |
Frequency of operation | The number of times that the ecm checks for malfunctions per driving
cycle.
"Once per driving cycle" means that the ecm detects malfunction only 1 time during a single driving cycle. "Continuous" means that the ecm detects a malfunction every time the enabling condition is met. |
Duration | The minimum time that the ecm must sense a continuous deviation in the monitored value(s) before setting a dtc. This timing begins after the "typical enabling conditions" are met. |
Malfunction thresholds | Beyond this value, the ecm will conclude that there is a malfunction and set a dtc. |
Mil operation | Mil illumination timing after a defect is detected.
"Immediate" means that the ecm illuminates the mil the instant the ecm determines that there is a malfunction. "2 Driving cycle" means that the ecm illuminates the mil if the same malfunction is detected again in the 2nd driving cycle. |
Component operating range | Normal operation range of sensors and solenoids under normal driving
conditions.
Use these ranges as a reference. They cannot be used to judge if a sensor or solenoid is defective or not. |

Mass or volume air flow circuit
Description
The mass air flow (maf) meter is a sensor that measures the amount of air
flowing through the throttle
valve.
The ecm uses this information to determine the fuel injection time and to
provide the appropriate air-fuel
ratio.
Inside the maf meter, there is a heated platinu ...
