Mazda 2: Engine Tune-up
Engine Tune-up Preparation
NOTE:
- If the accelerator pedal is depressed continuously for a specified time,
the engine speed
may decrease to the idle speed. This is due to the fuel cut control
operation, which
prevents overheating, and it does not indicate a malfunction.
1. Verify the following:
- ATX: Selector lever is in P or N position.
- MTX: Shift lever is in neutral position.
2. Warm up the engine to normal operating temperature.
- Increase the engine speed to 2,500-3,000 rpm until the cooling fan
starts
running.
- When the cooling fan starts running, release the accelerator pedal and
wait
until the cooling fan stops running.
3. Turn off all electrical loads.
4. Connect the M-MDS to the DLC-2.
Idle Speed Inspection
NOTE:
- Idle speed is not adjustable.
- Idle speed verification requires M-MDS.
1. Complete the engine tune-up preparation. (See Engine Tune-up Preparation).
2. Verify that the idle speed (M-MDS: RPM PID) is within the specification.
Idle speed (ATX: P, N position , MTX: Neutral position)
Ignition Timing Inspection
NOTE:
- The ignition timing cannot be adjusted.
- The M-MDS is required to verify the ignition timing.
1. Complete the engine tune-up preparation. (See Engine Tune-up Preparation).
2. Verify the ignition timing (M-MDS: SPARKADV) using the PID/data monitor
function of the
M-MDS.
