Does the P0118 indicate the coolant sensor needing replacement? Do both the P0172 and P0175 indicate both O2 sensors need to be replaced?

Codes:





16502

P0118

Engine Coolant Temp.Circ High Input





16556

P0172

Fuel Trim,Bank1 System too Rich





16559

P0175

Fuel Trim,Bank2 System too Rich

Thanks for the help.

 

The first code is pretty much a surefire coolant temp sensor.

Most likly the other two arent o2 sensors. I would start by checking things that would effect both banks. Maf, dirty air filter,

 

stopped up suction jet pump for rich codes

 

I would check your coolant reservoir and see if the connector is ok and there is enough coolant. As for the rich codes that motor do you have?

 

I have the 2.7T engine.
