01/11/2012· Hello. I have a 2001 Mercury Cougar DOHC. I have replaced the pump (just the base pump), plugs, wires, EGR, DPFE,FF, and have the injectors pulled right now for cleaning. This is a BP bad gas car. All those things were replaced prior to me getting the car as these did not fix the car. The only code that pops up is the Fuel Rail Sensor ...
06/07/2007· If you still get the same code with the new O2, then you''re outta luck and the manifold (with its defective catalyst) has to be replaced. DPFE sensor is a 40 part and can be replaced by a fairly novice individual. It''s position under the EGR valve makes it somewhat of a pain to get to, but it''s only 2 bolts, a single harness, and 2 hoses that plug into it. Don''t get the hoses mixed It uses the pressure …
Hi, My 2000 Mercury Cougar has been showing the CEL for a while now. The guys at Autozone said the code was P0401 Insufficient EGR circulation. I took the car in for an estimate and the mechanic told me the DPFE/EGR pressure sensor was faulty and needed to be replaced. Since I wanted to learn more about fixing my car myself, I looked the DIY ...
An expert that got 5 achievements. Re: I have a 99 couger with code P0401. I changed the egr... First you need to reset the computer. Disconnect the NEG battery cable for 10 minutes, you could have fixed the problem and the old errors are still being reported. If the same code resets, the problem is the vacuum passage below the airhorn.

02/08/2011· CASE 1: If the engine idle grew worse as you applied vacuum with the vacuum pump and the vacuum pump''s gauge needle stayed steady, then this result indicates that the EGR valve is working correctly and that the EGR passages in the intake manifold (and in the EGR valve itself) are not blocked with next step is to verify that the DPFE sensor is working correctly. Leave the vacuum …

01/03/2020· Have a 2005 Mercury Montego mileage was 119622 and had a repair shop run a diagnosis which the codes came out as p0109, p0171, p0174, p0430, p1719, p061f, p2106s and he supposedly replaced with a new …
07/01/2016· The exhaust gas recirculation system, also known as the EGR system, is an emission system that is found on many road going cars and trucks. Its purpose is to recirculate exhaust gases that have exited the engine, back into the intake manifold so that they can be reburned. This dilutes the amount of oxygen coming into the engine by replacing some of it with inert gases, which reduces the …
Reduced Gas Mileage Without accurate timing information, fuel injection won''t occur as efficiently as it should. That means the engine will need to use more gas and your morning commute will use up more fuel than usual. Engine Misfires Lack of proper spark timing can cause a different problem: one or more of the cylinders may misfire. That is to say combustion may be disrupted. You will feel, and maybe hear, …
I should mention that EGR valves rarely go bad. I have seen many cars come in for diagnosis with EGR system codes and a new EGR valve already installed! Don''t make this mistake! Okay, back to the tests! So with the vacuum line disconnected (and the engine still running), recheck your reading on the DPFE sensor. If it is now in spec, then your ...
