Starter Relay Circuit High Voltage
The P0617 code indicates that the Powertrain Control Module (PCM) has detected a voltage higher than the specified range in the starter relay control circuit. This can be caused by a short to voltage in the wiring, a faulty starter relay, or a malfunctioning PCM. The starter relay is responsible for supplying power to the starter solenoid when the ignition key is turned to the start position. A high voltage condition may prevent the relay from operating correctly, leading to starting issues.
01. Most Common Causes
- Short to voltage in the starter relay control circuit
- Faulty starter relay
- Corroded or damaged wiring/connectors
- Malfunctioning PCM
02. Symptoms You Will Notice
- Engine cranks slowly or does not crank
- Starter stays engaged after engine starts
- No start condition
- Check Engine Light illuminated
03. Step-by-Step Diagnosis
Step 1: Use a scan tool to confirm the code and check for other related codes.
Step 2: Visually inspect the starter relay and its wiring for damage, corrosion, or loose connections.
Step 3: Test the starter relay using a multimeter to check for proper resistance and operation.
Step 4: Check for voltage at the relay control circuit from the PCM; if voltage is high, trace the short to voltage.
Step 5: If all else is normal, test the PCM for faults or reprogram if necessary.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive with this code as it can cause starting problems or leave you stranded. The starter may fail to engage or remain engaged, potentially damaging the starter or flywheel.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for parts and labor, depending on the cause. Replacing a relay is inexpensive, but wiring repairs or PCM replacement can be more costly.
