DTC P1340 Camshaft Position Sensor "A" (Bank 1 Sensor 2)
DTC P1341 Camshaft Position Sensor "A" (Bank 1 Sensor 2 )

DESCRIPTION

DTC Detection Condition:

The camshaft position sensor (G signal) consists of a magnet, iron core and pickup coil.

The camshaft drive gear (LH) has 3 teeth on its inner circumstance. When the camshaft gear rotates, air gap changes between the protrusion on the gear and the pickup coil. The change affects the magnetic field and results in changes in the resistance of the MRE element.

The crankshaft signal plate has 32 teeth and is mounted on the crankshaft. The crankshaft position sensor generates 32 signals at every engine revolution. The ECM detects the standard crankshaft angle based on the G signal and the actual crankshaft angle and the engine speed by the NE signal.

Component Operating Range:

The camshaft position sensor (G signal) consists of a magnet and MRE element.

The camshaft drive gear has 5 teeth on its inner circumference. When the camshaft gear rotates, air gap changes between the protrusion on the gear and the pickup coil. The change affects the magnetic field and results in changes in the resistance of the MRE element. The crankshaft angle sensor plate has 32 teeth and outputs 32 signals at every engine revolution. The ECM detects the standard crankshaft angle based on the G signal and actual crankshaft angle and engine speed by NE signal.

INSPECTION PROCEDURE

HINT: Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air/fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
