Description
The camshaft position (cmp) sensor consists of a magnet and an iron core which is wrapped with copper wire, and is installed onto the cylinder head. When the camshaft rotates, each of 3 teeth on the camshaft passes through the cmp sensor. This activates the internal magnet in the sensor, generating a voltage in the copper wire. The camshaft rotation is synchronized with the crankshaft rotation. When the crankshaft turns twice, the voltage is generated 3 times in the cmp sensor. The generated voltage in the sensor acts as a signal, allowing the ecm to locate the camshaft position. This signal is then used to control ignition timing, fuel injection timing, and the vvt system.
Hint:
Dtc p0340 indicates a malfunction relating to the cmp sensor (+) circuit (the wire harness between the ecm and cmp sensor, and the cmp sensor itself).
Reference: inspection using an oscilloscope
Hint:
Monitor description
If no signal is transmitted by the cmp sensor despite the engine revolving, or the rotation of the camshaft and the crankshaft is not synchronized, the ecm interprets this as a malfunction of the sensor.
If the malfunction is not repaired successfully, a dtc is set 10 seconds after the engine is next started.

Inspection procedure
Hint:
Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.
Standard resistance
Hint:
Terms cold and hot refer to the temperature of the sensor. Cold means approximately -10° to 50°c (14 °to 122°f). Hot means approximately 50° to 100°c (122°to 212°f).
Standard resistance (check for open)
Standard resistance (check for short)
Ok: sensor is installed correctly.
Ok: camshaft teeth do not have any cracks or deformation.
Hint:
If the engine does not start, replace the ecm.
Compressor solenoid circuit (2006/01- )
Description
In this circuit, the compressor receives a refrigerant compression demand
signal from the air conditioning
amplifier. Based on this signal, the compressor changes the degree of
refrigerant compression.
