DTC P0340 CAMSHAFT POSITION SENSOR ”A” CIRCUIT (BANK 1 OR SINGLE SENSOR)
DTC P0341 CAMSHAFT POSITION SENSOR ”A” CIRCUIT RANGE/PERFORMANCE (BANK 1
OR SINGLE SENSOR)
CIRCUIT DESCRIPTION
The Camshaft Position (CMP) sensor consists of a magnet and an iron core which is wrapped with coppe\
r
wire, and is installed on 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 con\
trol ignition tim-
ing, fuel injection timing, and the VVT system.

HINT:
DTC P0340 indicates a malfunction related to the CMP sensor (+) circuit (the wi\
re harness between
the ECM and CMP sensor, and the CMP sensor itself).
DTC P0341 indicates a malfunction related to the CMP sensor (–) cir\
cuit (the wire harness between
the ECM and CMP sensor, and the CMP sensor itself).
Reference: Inspection using the oscilloscope.
HINT:
The correct waveform is as shown on the left.
G2+ stands for the camshaft position sensor signal, and
NE+ stands for the crankshaft position sensor signal.
