Evaporative Emission (EVAP) Canister Purge Regulator Valve 2, Checking
Solenoid valve is closed when no voltage is present.
Recommended special tools and equipment
- V.A.G1526 multimeter or V.A.G1715 multimeter
- V.A.G1594 connector test kit
- Wiring diagram
Test requirements
- Fuses in E-box (plenum chamber, left) must be OK
- Motronic Engine Control Module (ECM) Power Supply Relay -J271- -position A3- must be OK, check
- Ground (GND) connections between engine and chassis must be OK.
- Ignition switched off.
Test sequence
- Remove right rear wheelhousing liner.
- Disconnect 2-pin connector from Evaporative Emission (EVAP) Canister Purge Solenoid Valve -N115- (-1-).
Checking resistance
- Measure resistance between terminals of solenoid valve.
Specified value: 15.0 to 35.0 ohms
If specified value is not obtained:
- Replace Evaporative Emission (EVAP) Canister Purge Solenoid Valve -N115-.
- Erase DTC memory of Engine Control Module (ECM), Diagnostic mode 4: Reset/erase diagnostic data. Diagnostic Mode 04 - Erase DTC Memory
- Generate readiness code. Readiness Code
If specified value is obtained:
- Check wires.
Checking wiring
- Connect test box to control module wiring harness, connect test box for wiring test. Test Box, Connecting For Wiring Test
- Check wire between test box socket 45 + 2-pin connector terminal 2 for open circuit according to wiring diagram.
Wire resistance: max. 1.5 ohms
- Also check the wire for short circuit to B+ and Ground (GND).
Specified value: infinity ohm
- Check wire between 2-pin connector terminal 1 and Motronic Engine Control Module (ECM) Power Supply Relay -J271- for open circuit according to wiring diagram.
Wire resistance: max. 1.5 ohms
- Erase DTC memory of Engine Control Module (ECM), Diagnostic mode 4: Reset/erase diagnostic data. Diagnostic Mode 04 - Erase DTC Memory
- Generate readiness code. Readiness Code
If no malfunctions are found in wires:
- Replace Motronic Engine Control Module (ECM) -J220-.
