P0340

Wiring Diagram:

SYSTEM DESCRIPTION
CMP sensor detects REF signal and POS signal.
- REF signal: 6 pulses/1 revolution of camshaft. Each of REF signals has different wavelength. Based on REF signal, ECM (PCM) judges which cylinder is at TDC.
- POS signal: 360 pulses/1 revolution of camshaft. Each of POS signals has equivalent wavelength. Based on POS signal, ECM (PCM) judges the wavelength of REF signals, engine speed and piston position.

DTC CONFIRMATION PROCEDURE

NOTE:
Check to make sure that the following conditions are satisfied when using this DTC CONFIRMATION PROCEDURE.
- Intake air temperature: between -14 °C and 70 °C (6.8 °F and 158 °F)
- Atmospheric pressure: higher than 560 mmHg (Altitude: lower than 2790 m (9150 ft))
- he following DTC is not detected: P0335

1. With ignition switch OFF, connect scan tool.
2. Turn ON ignition switch and clear DTC by using scan tool if any.
