DTC 616 - EVAP Canister Shut-Off Valve Signal

WARNING: This page is about a different car, the 1996 Volvo 850. However, it is still accessible from the selected car via links, so may be relevant.
  1. Check status message on Volvo Scan Tool (998-8686 ). If fault is PERMANENT, SIGNAL TOO HIGH, go to next step. If fault is PERMANENT, SIGNAL TOO LOW, check for short circuit to ground in wiring between solenoid valve terminal No. 2 and ECM connector terminal A37. If fault is PERMANENT, SIGNAL MISSING, go to step 3). If fault is INTERMITTENT, SIGNAL TOO HIGH, check wiring for a short to voltage between EVAP canister shut-off valve connector terminal No. 2 and ECM connector terminal B19. If fault is INTERMITTENT, SIGNAL TOO LOW, check wiring for a short to ground between EVAP canister shut-off valve terminal No. 2 and ECM connector terminal B19. If fault is INTERMITTENT, SIGNAL MISSING, go to step 6).
  2. Turn ignition off. Remove left front wheelwell. Disconnect EVAP canister shut-off valve connector. Turn ignition on. Connect test light between shut-off valve connector terminal No. 2 and ground. If test light does not come on, replace EVAP canister shut-off valve. If test light comes on, check for short circuit to voltage in wiring between EVAP canister shut-off valve connector terminal No. 2 and ECM connector terminal B19.
  3. Turn ignition off. Remove left front wheelwell. Disconnect EVAP canister shut-off valve connector. Turn ignition on. Connect voltmeter between EVAP shut-off valve connector terminal No. 1 and ground. If battery voltage is present, go to next step. If battery voltage is not present, check wiring for an open circuit between EVAP shut-off valve terminal No. 1 and main relay.
  4. Ensure ignition is off. Connect ohmmeter between EVAP canister shut-off valve terminals No. 1 and 2. If ohmmeter reads 14-20 ohms, go to next step. If ohmmeter does not read 14-20 ohms, replace EVAP canister shut-off valve.
  5. Connect breakout box to ECM connector. Connect ohmmeter between breakout box pin No. 19 and EVAP canister shut-off valve connector terminal No. 2. If ohmmeter reads about zero ohms, DTC was caused by poor terminal contact at ECM or EVAP canister shut-off valve. Repair as necessary. If ohmmeter does not read about zero ohms, check for open circuit in wiring between EVAP canister shut-off valve terminal No. 2 and ECM connector terminal B19.
  6. Check EVAP canister shut-off valve and/or ECM connectors for loose connections, contact resistance or oxidation. Check wiring for an intermittent open circuit between EVAP canister shut-off valve terminal No. 1 and main relay terminal No. 3. Also check wiring for an intermittent open circuit between EVAP canister shut-off valve terminal No. 2 and ECM connector terminal B19.
