CAMSHAFT POSITION (CMP) SENSOR
YAA1F950
The Camshaft Position (CMP) sensor sends a CMP signal to the Engine Control Module (ECM). The ECM uses this
signal as a “synchronized pulse” to trigger the injectors in the proper sequence. The ECM uses the CMP signal to
indicate the position of the #1 piston during its power stroke. This allows the ECM to calculate true sequential fuel
injection mode of operation.

Circuit Description
The CMP sensor sends a cam position signal to the ECM. If the cam position signal is lost while the engine is running,
the fuel injection system shifts to a calculated sequential fuel injection mode based on the last fuel injection pulse, and
the engine continuous to run.
Camshaft Position Sensor Signal Voltage Inspection
1. Measure the voltage between the ECM terminal No. 11 and No. 106 while the engine speed is at idle.
Specified Value
1.2 ~ 1.7 v
Notice: The signal voltage will be changed in the range of 1.2 ~ 1.7 v.

Camshaft Position Sensor Output Wave Inspection
1. Measure the output wave between the ECM termi-
nals No. 104 and No. 106 using the scan tool or the
oscilloscope while engine speed is at idle.
Notice: Replace the CAM sensor if cannot get the out-
put wave as shown in the figure.

Camkshaft Position Sensor Power Supply Inspection
1. Disconnect the CMP sensor Connector.
2. Measure the resistance between the No. 1 and No. 3 pin of the CMP sensor connector while the ignition switch is in
“ON” position.
Specified Value
11 ~ 14 v
Notice: If the measured value is not within the specified value, check the cable.
