P0340 Camshaft Position Sensor \'A\' Circuit (Single Sensor)

General Information

Component Location





General Description

The Camshaft Position Sensor (CMPS) is a sensor that detects the compression TDC of the NO. 1 cylinder. The CMPS consists of a hall type sensor and a target on the end of the intake camshaft. When the target triggers the sensor, the sensor voltage is 5 V. If not, the sensor voltage is 0 V. These CMPS signal is sent to the ECM and the ECM uses the CMPS signal for synchronizing the firing of sequential fuel injectors.

DTC Description

If ECM detects that cam event signal count is over 3 under detecting condition, ECM sets P0340. And MIL (Malfunction Indication Lamp) turns on.
