INSPECTION

Note. "Cold" and "Hot" in these sentences express the temperature of the sensors themselves. "Cold" is from - 10° C (14° F) to 50° C (122 °F) and "Hot" is from 50° C (122° F) to 100° C (212° F).

Scheme 3

1. REMOVE THROTTLE BODY COVER
2. REMOVE INTAKE MANIFOLD ASSEMBLY (See «REMOVAL»(ref-227588-S25800526872006040600000) )
3. INSPECT VVT SENSOR RESISTANCE Disconnect the VVT sensor connector. Using an ohmmeter, measure the resistance between the terminals. Resistance: RESISTANCE REFERENCE Cold 835 to 1,400 ohm Hot 1,060 to 1,645 ohm If the resistance is not as specified, replace the sensor. Reconnect the VVT sensor connector. Connect the VVT sensor connector.
4. REINSTALL INTAKE MANIFOLD ASSEMBLY (See «INSTALLATION»(ref-227588-S19260811062006040600000) )
5. REINSTALL THROTTLE BODY COVER

Scheme 5

Scheme 6

1. WARM UP ENGINE Allow the engine to warm up to normal operating temperature.
2. CONNECT HAND-HELD TESTER Connect a hand-held tester to the Controller Area Network Vehicle Interface Module (CAN VIM). Then connect the CAN VIM to the Date Link Connector 3 (DLC3). Please refer to the hand-held tester operator's manual for further details.
3. INSPECT FUEL CUTOFF RPM OPERATION Increase the engine speed to at least 2,500 RPM. Check for injector operating noise. Check that when the throttle lever is released, injector operation noise stops momentarily and then resumes. HINT: The vehicle should be stopped. Measure with the A/C OFF. Fuel return speed: 1,400 RPM Disconnect the hand-held tester and CAN VIM from the DLC3.
