Signal Wire, Checking

Signal Wire, Checking







- Connect multimeter for voltage measurement as follows:

Harness connector Terminal Measure to
2 Engine Ground (GND)

- Switch ignition on.
- Specified value: approx. battery voltage
- Switch ignition off.

Checking Ground (GND) wire







- Connect multimeter for voltage measurement as follows:

Harness connector Terminal Measure to
3 B+

Specified value: about 10 V

If all specified values are being reached and the LED does not blink (measured between terminal 1 and 2 with starter and connector connected):
- Replace Camshaft Position (CMP) sensor.

If specified values are not obtained:

Checking wire connections between Camshaft Position (CMP) sensor and Engine Control Module (ECM)
- Connect test box to wiring harness of Engine Control Module (ECM), ECM is not connected. Test Box, Connecting For Wiring and Component Test
- Check the following wire connections for open circuit according to wiring diagram.







- Camshaft Position (CMP) Sensor 2 -G40- (bank 1)

Harness connector Terminal Test box Socket
1 (B+) 98
2 (signal) 87
3 Ground (GND) 108

- Camshaft Position (CMP) Sensor 2 -G163- (bank 2

Harness connector Terminal Test box Socket
1 (B+) 98
2 (signal) 86
3 Ground (GND) 108

Specified value: Wire resistance max 1.5 Ohms.

- Check wires for short circuit to each other as well as to B+ and Ground (GND).
- Specified value: Infinite Ohms. (no continuity)
- If necessary, repair wire connection.

Assembly is performed in the reverse order of removal, note the following:
- Check coolant level.

Final procedures
After repair work, the following work steps must be performed in the mentioned sequence:
1. Check DTC memory see "Mode 3: Check DTC memory". Mode 3: Check DTC Memory
2. If necessary, erase DTC memory see "Mode 4: Reset/erase diagnostic data". Mode 4: Reset/Erase Diagnostic Data
3. Generate readiness code. Readiness Code, Generating

- End diagnosis and switch ignition off.
