Engine Coolant Over Temperature Condition

What it means

P0217 is defined as "Engine Coolant Over Temperature Condition". the engine control module stores it when the monitored condition for this component or system is outside the limits programmed by the manufacturer.

This entry is compiled automatically from the standard definition and typical diagnostic practice for this type of fault. A detailed, reviewed article is in preparation.

Symptoms

• Check engine light on
• Rough or unstable idle
• Hesitation or poor acceleration
• Increased fuel consumption
• Possible limp mode with reduced power

Common causes

1. Engine Coolant Over Temperature Condition worn, contaminated or out of calibration
2. Mechanical problem in the system the sensor measures
3. Air, vacuum or exhaust leak influencing the reading
4. Wrong or low-quality replacement part
5. Wiring resistance causing a small voltage offset

How to diagnose

1. Compare the live Engine Coolant Over Temperature Condition reading with a known-good value or a second sensor at idle and at 2500 rpm
2. Check for air, vacuum or exhaust leaks that could skew the reading
3. Inspect the component for contamination and clean it if the design allows
4. Verify the part number is correct for the engine
5. Replace the Engine Coolant Over Temperature Condition if the reading remains out of specification

Symptoms linked to this code
