News November 19, The Fastest Growing Tire Category in Canada Three out of four Canadian motorists are using winter tires, and the vast majority of those winter tire owners are convinced their tires have saved them from a potentially hazardous driving situation. Ford has had the truck for 2 weeks now and still have no answers.

First diagnose P FORD code. Check the "Possible Causes" listed above.
Visually inspect the related wiring harness and connectors. Check for damaged. I need help, Ford ezplorer won't start at park and neutral shift, when diagnose these are the codes appeared 1. P FORD - Fuel Rail Pressure Sensor.
The FRP sensor measures the pressure difference between the fuel rail and atmospheric pressure. If the voltage is near battery voltage and the fuel pressure is low, this would indicate the fuel pump is failing or the fuel filter is badly restricted.

Log In. If there is less than battery voltage on this wire, voltage checks will need to be done to determine where the voltage drop is coming from.
Although the FRPS seldom fails, it can send a false reading to the PCM indicating that the fuel pressure is actually higher than it really is. Find More Posts by Todd W.
