OBD-II Generic Error Code P0617: How to Fix It

Q: Can I drive with error code P0617?

It is not recommended. P0617 can cause starting problems or stalling, making the vehicle unsafe to drive. Have it diagnosed and fixed promptly.

Q: Will P0617 clear itself?

The code may clear temporarily if the issue is intermittent, but it will return unless the root cause is repaired. A permanent fix is needed.

Q: How do I test a starter relay?

Use a multimeter to check resistance across the coil terminals (should be 50-100 ohms). Apply 12V to the coil and listen for a click, then verify continuity between the switch terminals.

Q: What causes P0617?

Common causes include a faulty starter relay, short to power in the relay circuit, damaged wiring, or a defective PCM.

Q: Can a bad starter cause P0617?

Yes, a failing starter motor can draw excessive current and cause voltage irregularities, triggering P0617. However, the code specifically points to the relay circuit.

Abstract

Error code P0617 means the powertrain control module (PCM) has detected a high voltage condition in the starter relay circuit. This usually indicates a short to power or a faulty relay, which can prevent the engine from cranking properly.
