2000 Honda Odyssey EX from North America - Comments

I own a 2000 EX Odyssey, at 90000 miles the Check EGR light came on. Just remembered at 30000 miles, the EGR passage port was blocked and a modification was done (putting a new tube insert etc) by the dealer under recall. Sure enough, after taking out the air-box and examined the passage, it was almost blocked again. With a drill to carefully remove the carbon, the Check EGR light stay off since then. My EX is at 105000 miles now. Hope this help other people.

Just to mention that I bought a Actron CP9175 to read and rest the CEL codes. Worth every penny.

Also my friend's EX had the transmission replaced with fewer mileage than mine. I notice that he never use the parking brake. My thought is, may be he is using the transmission to "lock " the van, since this is a rather heavy van, this may drive the transmission into early grave.

I'm having the P0420 error. My state does not check emissions. Should I worry about these codes?

I have a 2000 Odyssey EX with 115K.

Last year I paid the $1000 to have my CC replaced at inspection. About 1 week later the CEL light came back on, and I brought it back to the dealership. The dealership informed me that the CEL was defective, and the CEL has been on for the past year.

I am now back at the dealer for my 2008 inspection and they are saying I need a new throttle box ($660) and a new transmission. After reading all these posts, all I want to do is get the CEL reset, bring it to a gas station, get it inspected and run it into the ground (or at least until next inspection). I now realize that I am not unique in my situation.

After you reset with CP9175, does the CEL come on again or did you pass the inspection?

I can reset the CEL by disconnecting the battary. But the CKL will come on very soon.

Thanks.

I agree with previous poster. For about $70 (on sale at Meijers (like a Walmart) ), I bought an Actron CP9125 to read and reset the codes. About the size of a large cell phone. I keep it in the glove box. Used it dozens of time. Have become more popular with my friends.

Potential hammer-rapping cure for P0420 problem (see March 23 posting). Now almost four weeks and no return of the CEL light. Awesome.

I have a 2000 Odyssey.. It now has 120,000 miles. I have had problems since it had 1542 miles.. I constantly have shaking in the front end.. This van has had 4 sets of tires.. 3 transmissions... catalytic converter replaced.. problems with the doors... The front end problems is what is driving me crazy. The tire people say it's the alignment, and the Honda people say it's the tires.. Has anyone experienced this same problem?

00 EX has 108K with Honda warranted remanufactured transmission at 96K. I started driving not above 55 mph and pushing the gas pedal gently as possible. The CEL has been off for few weeks and I got 22 mpg from 20 mpg. The brand name gas seems to be helping. Will try the hammer solution suggested next time the CEL comes on.

Wow! Glad I found this site! As for me, I'm staying toasty warm down in here southern Arizona, where we care less about such trivial things as a check engine light.

I definitely appreciate the post about which code reader to buy and the hammer method of clearing the CEL.

Well, I might be the only one here that, as of today, still loves his Honda Odyssey! I bought it from the dealership in December 2005, with 93,000 miles on it. I've driven a lot of miles on it and currently have about 165,000 (that's about 72,000 miles in about 2.5 years). When I bought it, the dealership had to replace the O2 sensors to clear the CEL but it's come off and on ever since. Dealership mechanic told me at the time that, yes, it will slightly affect gas mileage but you can still "drive it like you stole it". Since then, I've been faithfully changing the oil and doing maintenance as required.

Granted, I do intend on taking it into the dealership because it currently has the CEL on, the Maint Required on (probably because the last oil change place didn't clear it or something), and the TCS light is on, but I'm still getting about 22 to 23 miles to the gallon on the highway (averaging about 80 to 85 mph...yes...I speed slightly).

Again, thanks for ALL the good info on this site! Glad to have found it!.

Proposed hammer solution for P0420 catalytic converter CEL issue... worked for about six weeks, then light came back on. Prior to this temporary "fix", the P0420 CEL code was coming back on every couple days. So, I still believe this brute force method may help bring a CC that is operating just outside of spec back into spec for a little while, perhaps long enough to meet inspection requirements, but it is at best a temporary solution. Sorry!

After market Catalytic Converters for Honda Odyssey - my rear wheel bearing on my 2000 Honda Odyssey went bad (150,000+ miles) on a long trip. Fixed in Charlotte, NC. In conversation, the owner of the repair shop asked about my CEL light. I mentioned that it was a P0420 CC code that was coming up from time to time. Regarding after-market CC, he cautioned me... there are two types of after-marker CC's... 1) a "universal" CC, and 2) after-market CC specific to a make/model. He said that the "universal" ones don't work in many situations (ex. Honda Odyssey). Avoid trying to install a "universal" after-market CC on the Odyssey - get one that is specific to this vehicle.

I went to Midas and had the ERG valve, spark plugs and cc replaced. I didn't want to pay Honda twice as much. The CEL was off a month. Took the van back and they replaced the rear oxygen sensor. That lasted 50 miles.

I took it back and they said the EGR valve was defective. The mechanic said he ran a scope on the van etc and the light wouldn't come back on. 60 miles later the CEL came back on. I read on a post somewhere that it takes about 50 miles for the computer to get results, so I think they may just be resetting the codes. I am about to give up and put some tape over the light, and when I have emissions tested I will clear the codes and hopefully it will pass. I must admit that for the first 98000 miles I didn't have a problem with the van.

My 1999 Odyssey is experiencing the same CC issues that have been listed on this site. I was wondering if anyone could provide me with the phone # they used to get through to someone at Honda. There are many phone #'s...not sure which one was used to get Honda to cover the cost on the CC part and just pay for labor.

Also, for those folks who were able to get Honda to cover cost of the parts, are you original owners or 2nd owners of your vehicles.

I bought this used from a private party, so not sure if Honda would be willing to work with me to defer some of the cost of replacing the CC.

My inspection is coming up soon...I'm hoping to resolve this issue quickly by at least getting the CEL light turned off long enough to pass inspection and maybe trade this van in.

Thanks...

Please tell me more about what you did. "after taking out the air-box and examined the passage, it was almost blocked again. With a drill to carefully remove the carbon, the Check EGR light stay off since then. My EX is at 105000 miles now. Hope this help other people."

What do you mean "air box" and where do you put the bit? I have read the Honda bulletin concerning the repair and pipe placement. That procedure involves removing the intake manifold. I am concerned that you have the EGR problem again even after the modification was made. I would like to try "cleaning" mine before spending the money at the dealer. My Odyssey is a 2000 LX with 160K. Thanks for the help.
