Ignition Timing: Testing and Inspection
2006 Toyota Sequoia 4WD V8-4.7L (2UZ-FE)SECTION Testing and Inspection
CHECK IGNITION TIMING
a) Warm up engine.
1) Allow the engine to warm up to normal operating temperature.
b) Inspect ignition timing (When using a intelligent tester).
1) Connect a intelligent tester to the Controller Area Network Vehicle Interface Module (CAN VIM). Then connect the CAN VIM to the Date Link Connector 3 (DLC3).
2) Please refer to the intelligent tester operator's manual for further details.
Ignition timing: 5 to 15° BTDC at idle (Transmission in neutral)
3) Disconnect the intelligent tester and CAN VIM from the DLC3.
c) Inspect ignition timing (When not using a intelligent tester).
1) Connect the tester probe of a timing light to the wire (black - red) of the ignition coil connector for the No. 1 cylinder.
2) Using SST, connect terminals TC and CG of the DLC 3.

3) Using a timing light, check the ignition timing.
Ignition timing: 5 to 15° BTDC at idle (Transmission in neutral)
4) Remove the SST from the DLC 3.

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.
