DTC P0340 CAMSHAFT POSITION SENSOR ºAº
CIRCUIT (BANK 1 OR SINGLE SENSOR)
DTC P0341 CAMSHAFT POSITION SENSOR ºAº
CIRCUIT RANGE/PERFORMANCE (BANK 1
SINGLE SENSOR)
CIRCUIT DESCRIPTION
The camshaft position sensor (G2 signal) consists of a magnet, iron core and pickup coil.
The G2 signal rotor has 3 teeth on the outside and is mounted on the intake camshaft.
When the camshafts rotate, the protrusion on the signal plate and the air gap on the pickup coil changes,
causing fluctuations in the magnetic field and generating an electromotive force in the pickup coil.
The NE signal plate (crankshaft position sensor plate No. 1) has 34 teeth and is installed on the crankshaft.
The NE signal sensor generates 34 signals at every engine revolution. The ECM detects the crankshaft
angle and the engine revolution based on the NE signal, and the cylinder and the angle of the VVT based
on the combination of the G2 and NE signal.
DTC No.DTC Detection ConditionTrouble Area

ing for 4 sec. or more (2 trip detection logic).

INSPECTION PROCEDURE
HINT:
Read freeze frame data using the hand±held tester. Freeze frame data records the engine conditions when
a malfunction is detected. When troubleshooting, it is useful for determi\
ning whether the vehicle was running
or stopped, the engine was warmed up or not, the air±fuel ratio was lea\
n or rich, etc. at the time of the mal-
function.
1 INSPECT CAMSHAFT POSITION SENSOR(RESISTANCE)
(a) Disconnect the C1 camshaft position sensor connector.
(b) Measure the resistance between the terminals of the camshaft position sensor.
Resistance:
835 to 1,400 at cold
1,060 to 1,645 at hot
NOTICE:
ºColdº and ºHotº shown above mean the temperature of
the coils themselves. ºColdº is from ±10 C (14 F) to 50 C
(122 F) and ºHotº is from 50 C (122 F) to 100 C (212 F).

NOTICE:
Do the test at normal operation ATF temperature 50 to 80C (122 to 176F).
The line pressure test should always be carried out in pairs. One technician should observe
the conditions of wheels or wheel stopper outside the vehicle while the other is doing the test.
Be careful to prevent SST's hose from interfering with the exhaust pipe.
(1) Warm up the ATF.
(2) Remove the test plug on the left side of the trans-
axle case and connect SST.
