Range/Performance (Bank 2)
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 5V. If not, the sensor voltage is 0V. 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
Checking oputput signals from CMP during engine running, if the expected number of cam tooth count is not observed,
ECM sets P0346.
There is a memory reset function on GDS that can erase optional parts automatically
detected and memorized by ECM. Before or after testing ECM on the vehicle, use this
function to reuse the ECM on the others
