Replace or clean EGR?
2001 EX-V6 Accord with 170,000 miles. Just got a P0401 code. The check
engine light went out on it's own (TCS light was also on when this occurred) then lit up again a week later. Trying to find information on the procedure for cleaning the EGR. Not much out there. Found 1 article stating special tools are required. http://www.faqfarm.com/Q/How_do_you_...d_2000_V6_2_Dr Anybody attempt this with the standard tools one might find in a typical home garage? Trying to determine if I should attempt this myself or just buy a new EGR. They're expensive ($200 plus) but maybe not depending on how much effort it takes to clean and drill it out and what the special reamer costs, especially if I'm only going to use it one. Any insight from those experienced in this would be appreciated. |

Re: Replace or clean EGR?
Original Poster: Did you mean the valve itself? Or only the ports and
passageways? I have a follow-up question for the masses out there: I had the same prob where insufficient EGR Flow causes this P0401 code and we know the fix for it, but I was told that over time if not remedied it will fail the EGR valve...on the other hand I've also been told that these EGR valves pretty much never fail? Well do they? And is this true? Kevin High Tech Misfit wrote: > bbtaco wrote: > > > http://www.98exl.com/tsb/CG/99-085%2...20Clogging.pdf > > This won't do the OP any good.

Vehicle went 170k without being drilled, a good cleaning should buy me a lot more time. |

Before you start drilling, make sure the EGR valve or control unit isn't having problems. Insufficient vacuum or a leaky diaphragm might produce the same code. (I don't know that for sure!) Basic troubleshooting is straightforward. Get one of those hand vacuum pumps with a vac meter. Insert a 'T' fitting and monitor the the vacuum being provided to the valve while the car is in motion. Then remove the valve and use the pump to pull vac on the unit. Observe its motion, and watch for leaks. Note how much vac is required to lift the valve, and compare to the control box output. The system may not need full lift, but the valve should be at least partially open when the car is running. Also, check the rate of vacuum application. I chased my tail for several weekends troubleshooting a constricted EGR solenoid passage. The vac would arrive, and the valve would get opened, but not quickly enough to keep the ECU happy. If all this is working, then start thinking about drilling and reaming.... -Greg |

The system may not need full lift, but the valve should be at least partially open when the car is running. Also, check the rate of vacuum application. I chased my tail for several weekends troubleshooting a constricted EGR solenoid passage. The vac would arrive, and the valve would get opened, but not quickly enough to keep the ECU happy. If all this is working, then start thinking about drilling and reaming.... -Greg |

Before you start drilling, make sure the EGR valve or control unit isn't having problems. Insufficient vacuum or a leaky diaphragm might produce the same code. (I don't know that for sure!) Basic troubleshooting is straightforward. Get one of those hand vacuum pumps with a vac meter. Insert a 'T' fitting and monitor the the vacuum being provided to the valve while the car is in motion. Then remove the valve and use the pump to pull vac on the unit. Observe its motion, and watch for leaks. Note how much vac is required to lift the valve, and compare to the control box output.

Re: Replace or clean EGR?
All that is great but the problem is a common and well documented problem on
that engine. Honda drilled the port out and installed a coated sleeve to correct the problem. The only way to fix it is to remove the manifold and clean out the port. He could probably get the kit with sleeve from a dealer and have a dealer or mechanic install it if he does not have the ability to do it....
