Engine Coolant Temperature Sensor 6 Circuit Range/Performance

Where it lives

For P2BB7, start at the sensor the description names.

Check these first

• An engine coolant temperature sensor 6 reading outside the coolant range
• A failed sensor 6 with a slow or skewed response
• A sensor 6 that disagrees with the other coolant temperature sensors
• Air pockets at sensor 6 after a coolant service

What to do next

1. Scan all modules and compare sensor 6 to the other coolant temperature sensors
2. Inspect the sensor 6 connector and wiring for damage
3. Check for air pockets and bleed the cooling system
4. Measure sensor 6 resistance hot and cold against the coolant range
5. Replace engine coolant temperature sensor 6 if the reading stays skewed
6. Clear the code and retest
