P0675

What it means

An electrical fault is present in the glow plug circuit for cylinder 5. The glow plug control module cannot drive this plug correctly — open circuit, short, or out-of-range resistance — so cylinder 5 is not pre-heated. On a cold start this causes hard starting, white smoke, and a misfire-like rough run until the engine warms. Causes: a failed glow plug, a broken supply lead to that plug, corrosion at the plug connector, or a faulty module output for cylinder 5.

Is it safe to drive?

The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
