Ignition Timing: Testing and Inspection
Ignition Timing Inspection
Caution:
^ Do not change the crankshaft position sensor installation position. Changing the CKP sensor installation location while attempting to adjust the ignition timing could cause an engine malfunction.
Note:
^ The ignition timing cannot be adjusted.
^ The SST (M-MDS) is required to verify the ignition timing.
1. Warm up the engine.
(1) Turn off all electrical loads.
(2) Increase the engine speed to 2,500 - 3,000 rpm until the cooling fan starts running.
(3) When the cooling fan starts running, release the accelerator pedal and wait until the cooling fan stops running.
2. Connect the SST (M-MDS) to the DLC-2.
3. Verify the ignition timing (M-MDS: SPARKADV) using the PID/data monitor function of the SST (M-MDS).

4. Gradually raise the engine speed and verify that the ignition timing advances.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
