Circuit Description

The fuel heater improves starting in cold ambient conditions by heating the fuel to reduce its viscosity.

Component Location

The fuel heater is located on the fuel filter on the intake side of the engine.

Shop Talk

This fault could also indicate the fuel heater circuit is shorted to battery positive (+). This would command the fuel heater to be on full time. This will drain the batteries or burn out the fuel heater.
