We perform these tests on a daily basis and have all the expertise and equipment to diagnose your DPF fault quickly and accurately. If you do not have the ability or capability to carry out all of the tests, take your vehicle to a garage that can perform the tests correctly, it will be cheaper than ordering a vaporiser in error. Use a DMM to test the sensors either using resistance or voltage test methods.ĭo not order a vaporiser until you have carried out all the tests You may find only 2 of the 3 sensors has a data PID.
FORD DIAGNOSTIC TEST CODE
(Use a clean container to catch the fuel.) If fuel is present the pump and circuit are working. Simply match up the code on the left with its description. Actuate the pump using a suitable scan tool and check fuel flows out of the pipe going to the vaporiser.Measure the resistance of the vaporiser glow plug (it should be 1.1 Ohms).Connect a Mityvac to the vaporiser supply pipe, if it holds a vacuum the vaporiser is blocked.Exhaust gas temperature must exceed 600 degrees Celsius for the system to work effectively. The exhaust gas temperature is monitored via three temperature sensors fitted near the turbo, in front of the DPF and after the DPF. A separate pump fed from the fuel filter housing supplies the fuel to the vaporiser. The Vaporiser itself consists of a glow plug to heat the fuel and a nozzle to direct the fuel into the exhaust gas stream. The STI is the single pin connector on the EA, or the top left pin on the EBII-EL. STI/STO The Self Test Input (STI) and Self Test Output (STO) pins are used to enter diagnostic mode and read the output codes respectively.
FORD DIAGNOSTIC TEST SERIES
This series of engines use a vaporiser to increase exhaust gas temperatures to help with DPF regeneration. This guide only covers the KOEO test which is most helpful for reading stored codes. Clearing the code will not restore normal operation for long, although you may think the code has gone it will return once the vehicle completes its monitoring of the DPF operation. Please be aware that many EEC-IV ECU do not have a DCL bus line, such as mono injection, engines with mechanical ignition. If the Diagnostic Trouble Code P244C is stored in the engine control module of your Ford Diesel then your DPF is blocked and failing to regenerate. This is Java desktop project for petrol engine diagnostic for cars with Ford EEC-IV ECU with DCL communication data bus which goes from ECU pins number 18 and number 19 from total 60. Warning Lights Illuminated and the vehicle is in restricted performance mode
