DESCRIPTION
The camshaft position sensor (for exhaust camshaft) (EV1, EV2 signal) consists of a magnet and MRE (Magneto Resistance Element).
The exhaust camshaft has a timing rotor for the camshaft position sensor. When the exhaust camshaft rotates, changes occur in the air gaps between the timing rotor and MRE, which affects the magnetic field. As a result, the resistance of the MRE material fluctuates. The camshaft position sensor converts the camshaft rotation data to pulse signals, uses the pulse signals. The ECM uses the pulse signals to determine the camshaft angle. Then the ECM uses this data to control fuel injection duration, injection timing and the Variable Valve Timing (VVT) system.

Tech Tips
The correct waveform is as shown.
EV1 stands for the camshaft position sensor signal (for exhaust camshaft of bank 1), and EV2 stands for the camshaft position sensor signal (for exhaust camshaft of bank 2).
| ECM Terminal Name | CH1: Between EV1+ and VV1- CH2: Between EV2+ and VV1- |
| Tester Range | 5 V/DIV., 20 ms./DIV. |
| Condition | Idling with warm engine |
MONITOR DESCRIPTION
If the output voltage transmitted by the camshaft position sensor (for exhaust camshaft) remains low or high, the ECM interprets this as a malfunction in the sensor circuit, illuminates the MIL and stores a DTC.
MONITOR STRATEGY
| Required Sensors/Components (Main) | Camshaft position sensor |
| Required Sensors/Components (Related) | Crankshaft position sensor |
| Frequency of Operation | Continuous |
CONFIRMATION DRIVING PATTERN
Connect the GTS to the DLC3.
Turn the engine switch on (IG).
Turn the GTS on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the engine switch off and wait for at least 30 seconds.
Turn the engine switch on (IG).
Turn the GTS on.
Start the engine.
Idle the engine for 10 seconds or more.
Enter the following menus: Powertrain / Engine / Trouble Codes.
Read the pending DTCs.
Tech Tips
If a pending DTC is output, the system is malfunctioning.
If a pending DTC is not output, perform the following procedure.
Enter the following menus: Powertrain / Engine / Utility / All Readiness.
Input the DTC: P036511, P036515, P039011 or P039015.
Check the DTC judgment result.
| GTS Display | Description |
|---|---|
| NORMAL |
|
| ABNORMAL |
|
| INCOMPLETE |
|
Tech Tips
If the judgment result is NORMAL, the system is normal.
If the judgment result is ABNORMAL, the system is malfunctioning.

CAUTION / NOTICE / HINT
Tech Tips
Read Freeze Frame Data using the GTS. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
Bank 1 refers to the bank that includes the No. 1 cylinder*.
*: The No. 1 cylinder is the cylinder which is farthest from the transmission.
Bank 2 refers to the bank that does not include the No. 1 cylinder.
| DTC | Suspected Area |
|---|---|
| P036511, P036515 | Bank 1 |
| P039011, P039015 | Bank 2 |
