DTC P0340 CAMSHAFT POSITION SENSOR A CIRCUIT MALFUNCTION
(BANK 1 OR SINGLE SENSOR)
COMPONENT LOCATION
E96A3409
CMPS
LFIG297A
GENERAL DESCRIPTION
E8FD63BB
Cam Shaft Position Sensor(CMPS) is hall sensor type. Sensing the teeth attatch at the end of exhaust cam shaft, CMPS
detects rotation of Cam shaft (1 signal per 1 lotation)As Cam shaft rotates once while Crank shaft does twice, CMPS
referrence point generates once while CKPS’ do twice.As this signal inputted to ECM, it distinguishes crank angle and the
cylinder which requires fuel injection in order to determine injection sequence and duration.
DTC DESCRIPTION
EC75AD9D
P0340 is set when CMPS signal does not generate while CKPS signal is outputted for the duration that crank shaft rotates
4 times. This code is due to the failure relevant to CMPS related circuit and sensor component.
