RAM Diesel Error Code P0675: How to Fix It

Q: Can I drive my RAM with a P0675 code?

You can drive with this code, but expect hard starting especially in cold weather, rough idle, and increased emissions. The vehicle may also have reduced power and poor fuel economy.

Q: How much does it cost to fix P0675 on a RAM diesel?

If just the glow plug needs replacement, expect to pay $50-150 for parts and labor. If the glow plug control module is faulty, repair costs can range from $300-800 depending on the model year.

Q: What causes RAM glow plugs to fail?

Common causes include normal wear over time, carbon buildup, excessive heat cycles, electrical surges, poor fuel quality, and contamination from engine oil or coolant leaks.

Q: How long do RAM diesel glow plugs last?

RAM diesel glow plugs typically last 80,000-120,000 miles under normal conditions. Severe duty use, frequent cold starts, and poor maintenance can reduce their lifespan significantly.

Q: Will P0675 cause my RAM to fail emissions testing?

Yes, the P0675 code will likely cause your vehicle to fail emissions testing since it affects the diesel combustion process and increases harmful emissions output.

Abstract

The P0675 error code in your RAM diesel indicates a problem with the glow plug circuit for cylinder 5. This diagnostic trouble code means the engine control module (ECM) has detected an electrical issue in the glow plug system, which can cause hard starting, rough idle, and increased emissions.
