Have the code scanned then do a search here on Odyclub with the code (PXXXX). Autozone will rent a scanner for free or take to a Honda dealer for $80 diag. fee.

2001 Check engine light

Autozone ran the test and the codes were P1676 & P0740 does anyone know what that means?

Like New Dad New Van said, use the search feature of this site and look for posts pertaining to both the codes Autozone gave you. IIRC P1676 is PCM related and a pain in the rear to get rid of sometimes but just search and read up.

 

First check is to make sure you have a good battery and charging system as a weak battery can cause all kinds of wierd problems.
Are you past the extended warrenty on the transmission? If not take it to the dealer and have the P0740 checked out. It is a transmission code. If the P1676 code comes back after reset it is probably PCM time.

 

Take to your Honda dealer to seek Extended Warranty on the transmission or Goodwill if outside the 109,000 miles or 7 yrs 9 mos.

I'd be more confident if his D4 light flashed along with the TCS and CEL for a doomed tranny......like mine did at 102K. The incidences of factory replaced 99-01 trannys must be coming near a end by now????

 

Code P0740 & P1676

I have still been driving the van (not sure if I should be) but need to get to work. It runs and starts fine. The battery seems o.k. We were told to pull a fuse under the hood on the passenger side to make the check engine light go out and then see if it comes back on. We don't know which fuse. Tried a few but light is still on. We were told that the P1676 is Signal Line Failure, and that the 740 is lock-up contol system, what is that and is it something we can check?

 

What is your mileage? Did you see a Honda dealer?

 

Around 186,000 and no we have not been to the Honda dealer. That is always a very expensive trip and we were trying to see what we could find out first.

 

The problems you are seeing are not simple problems to fix. The P1676 is an internal PCM problem and if it comes back immediately after reset it is 99.9 percent chance you will need a new PCM and you will have to determine if you have enough ability to replace it. The P0740 Is a lock up problem in the torque converter and will probably need a new transmission. Reset the codes and if the light comes back on have the codes read to determine if one or both are coming back on.

 

How do we reset the codes?

 

Pull the #13 fuse out for 10 seconds from the passenger kick panel and reinsert.

Mine coded PO740 with the ABS, CEL, and D4 flashing. With restart only CEL remained. Tranny ran perfectly for the weekend awaiting arrival of replacement. Dealer basically stipulated it was going to fail very soon thereafter hence the pro active repair plan.

Just completed 20K miles on tranny #2 and DID drain / fill with last oil change (at 15K) with NO particles (grey) on the magnet, and the fluid color and smell normal. This is with the added ATF oil cooler and remote full sized filter installed. BTW, only cost $3 to replace the ATF full sized oil filter and this time the drain and fill was just a tad over 4 qts. due to the added capacity of the filtering system. I really believe this is going to keep the fluid very clean.

 

Can you tell me what Fuse #13 is listed as. Everyone on here is saying that fuse has fixed their door problems. Is it under the hood or in the van?

We were traveling in stop and start traffic and the TCS and check engine light came on. We stopped and when we restarted the car the TCS light went out but not the check engine light. Didn't know if something is really wrong or just a fluke, since the traffic. The van seems to be running fine.

Fuse panel is at the passenger right foot panel, and I recall it is labeled, "clock" something? Just make sure it IS #13.

Did your tranny slip or seem like it was in neutral and required significant pedal input to move...like it started in 2nd or 3rd gear?

 

o.k. will pull fuse this evening. No, the van seems to be running fine. Haven't noticed any difference in anything.

 

OK, hoping the CEL will stay off .... for at least awhile? If it returns quickly, have the codes checked to see what they are. And as William Wales said earlier, hope it is NOT a P1676....

 

Thanks. Found the fuse last night and the CEL is now off. It stayed off on the way to work but we will see how long that lasts.

 

Let us know your results.

Try this, turn the ignition to the position when the dash lights go on, and watch the CEL light, if it stays lit for about 10 seconds WITHOUT flashing, then you should be OK...if not count the flashes and let us know how many....

 

# of CEL flashes

With my CEL coming on, I pulled the #13 fuse as mentioned above and tried to retrieve the code/s. None reported.

Then, in my case, the CEL blinked once followed by 5 blinks in succession. What does that mean?

thanks,
bmamo

 

Everyone here seems to be hot on pulling fuse 13. IF you want to find out what caused the CEL you HAVE TO READ THE CODES BEFORE PULLING THE FUSE. Pulling fuse 13 resets the control unit and clears all information in it.

 

Little Knowledge is dangerous

Now that its evident that the codes are cleared by pullling #13 fuse out (used to be you'd disconnect the battery and wait a few minutes before you reconnect for the codes to clear), I'll certainly take more precaution

 

CEL & TCS back

While driving on the fwy last night the CEL and TCS came on again and upon restart the TCS went away while the CEL stayed. Pulled the only code which is P0740. No other lights flashed including D4 and van drove home fine 100 miles or so.

Unsure if its related to the last trip to the dealer when they replaced the IACV and a few days later the CEL and TCS came on the first time.

I havent noticed any trans slippage or other hesitation either. So will keep an eye and see what happens next.

Not too keen to take it to the dealer right now unless the van acts up. With 01 tranny recall, I have another year and lots of miles in case of a tranny failure.

Any suggestions?

Sorry but, if the D4 flashes and the tranny slips or seems like it is in "limp" mode along with your current scenario....it will be tranny change out time. Hopefully it will occur sooner than later? Good luck!

Ours did it at 102K, just in the nick of time (mileage wise).
