WARNING: This page is about a different variant/trim than selected.
- PERFORM ACTIVE TEST USING TECHSTREAM (OPERATE OIL CONTROL VALVE FOR INTAKE CAMSHAFT)
- Connect the Techstream to the DLC3.
- Start the engine and turn the tester on.
- Warm up the engine.
- Select the following menus: Powertrain/ Engine and ECT / Active Test / Control the VVT Exhaust Linear (Bank 1) or Control the VVT Exhaust Linear (Bank 2).
- Check the engine speed while operating the oil control valve using the tester.
OK
Tester Operation Specified Condition 0% (OFF) Normal engine speed 127% (ON) Engine idles roughly or stalls (soon after oil control valve switched from OFF to ON)
NG → See step 3
OK → See step 2
- CHECK FOR INTERMITTENT PROBLEMS. Refer to CHECK FOR INTERMITTENT PROBLEMS
- INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY
- Disconnect the exhaust camshaft timing oil control valve connector.
- Measure the resistance according to the value(s) in the table below.
Standard resistance
Tester Connection Condition Specified Condition 1 - 2 20°C (68°F) 6.9 to 7.9 Ω - Reconnect the camshaft timing oil control valve connector.
