Re: Need help ASAP....issues after maintenance OK.....so maybe the vehicle needs to run a couple full tanks of gas before it catches up =P I got 38 mpg out of my second tank today so, I am happy to see improvement. I havent had time to investigate the EVAP leak that is somewhere around the charcoal canister I installed. I just recieved my primary O2 sensor today and (low and behold!!!) it is different than the original even though the seller swore I was wrong...bastards! Anyway, below is the pick of the new primary O2 sensor. What do you guys think? It has a lot less of the milled holes in the sides, but definately has the extended head to get deeper into the headers. Comments anyone?[IMG]http://i1138.photobucket.com/albums/...6/IMAG0019.jpg[/IMG] |
Re: Need help ASAP....issues after maintenance still looks like the wrong sensor to me. its more like a secondary. is that the ntk? or did they just send another bosch. idk, i have a feeling check engine light will come back if you install that and wait a few days. |
Re: Need help ASAP....issues after maintenance I got some CEL codes today....I cleared them to see if they return. Two of them are for that damn EVAP leak that I cant find!!! I checked everything and there was nothing out of place, dry rotted, disconnected, or anything.....any ideas on how to troubleshoot that? The third was regarding the cat converter which quiet possibly means I cant use that damn primary O2 sensor. I was thinking it could be part #11 in the diagram below. When I was replacing the canister, the screws were frozen in and I had to hacksaw them out (even after heat and WD40 didnt help!). The bracket got slightly bent, but it still felt like it seated into place when everything was put back together. Do you think this could be the issue? http://www.hondaautomotiveparts.com/...L+PIPE+%281%29 ***I dont know how to post just the picture so if you go to the website, it is #11 VALVE, CANISTER VENT SHUT |
Re: Need help ASAP....issues after maintenance Specific EVAP codes? |
Re: Need help ASAP....issues after maintenance I cleared the codes and they have not reappeared in around 50 miles. I know they will come back because they only come on when the engine is completely cold (sitting all night), then I drive about 5 miles, than they come on. |
Re: Need help ASAP....issues after maintenance Yeah that sensor (the last pic posted thus far) doesn't look like an OEM/NTK primary sensor. |
Re: Need help ASAP....issues after maintenance I think I am going to go to Autozone and look at the part and maybe just buy it from them. Then I can call rockauto and complain about another bad product! I dont think they will like that, but I want the right part for my vehicle! BTW....the sensor in the above picture is supposed to be the Bosch 13532 |
Re: Need help ASAP....issues after maintenance yeah it not so...try local auto parts. the problem is when i got mine they hardly had any import parts so it was a special order. but being i worked at advance, i just did my own ordering and looked at the insides before buying. i guess if they order it and it looks wrong, you can refuse it. just say you want to pay when the part comes in instead of up front. what is the specific engine code? is it a sensor code or an actual catalyst code? if its the cat thats bad, no amount of sensors will help. |
Re: Need help ASAP....issues after maintenance I erased the codes because I assumed one of two things: They would come back quickly or They were faulty codes after new part installation. I commute 500 miles a week, so if there are issues, they will surely return. This damn primary O2 sensor is pissing me off though! LOL! |
Re: Need help ASAP....issues after maintenance You guys will love this....I went to autozone and looked at Bosch PN# 13532. Low and behold, it was DIFFERENT than the first two I got. That means I have seen 3 completely different O2 sensors all with the same part number, all in the same box. I have always thought very highly of Bosch until recently.... |
Re: Need help ASAP....issues after maintenance haha no more bosch parts for me. did the third one look like the stock sensor? |

ABSOLUTELY AMAZING how three of the same parts could be so different. I too was a die hard Bosch fan until now. I know there parts have always worked great in my Volkswagon and my Ford so....time will tell I guess. ------------------------------------------------------------------------- As far as the O2 sensor goes, the one that is currently in there seems to be working. It is actually idling and driving very nicely right now, and I have not pulled any CEL codes since I cleared the codes immediately after installation. I also checked out all the lines by the charcoal canister and firmly pushed in the hoses to ensure they were all tight. I am eager to see if any CELs come back, but so far so good ;) |

Anway, my CEL finally came back on and it pulled two codes, but they are both the same. One is active, the other says 'pending' on the scanner; I have never seen this before. The code is P1457. I am pretty sure it is the Canister Vent Shut (CVS)....I checked all of the lines, and could not find any leaks, loose connections, cracked lines, etc. The screws were frozen in place on the original so I hack-sawed them off, I guess it it possible that the CVS got damaged??? It is the only thing I can think of....... |
Re: Need help ASAP....issues after maintenance my primary was exactly the same as stock, even had "NTK" engraved in the base. this was from a bosch box about 3 yrs ago. and yeah sounds like something got damaged when you hacksawed it. |
Re: Need help ASAP....issues after maintenance OK....I will order the part and report back. I really hate replacing parts that I am unsure about....if it isnt the CVS I am gonna be pissed! I just hope this doesnt turn into a bottomless pit for that damn code! UPDATE: Ordered the CVS and the appropriate EVAP filter (the $20 one) |
Re: Need help ASAP....issues after maintenance FINALLY got the parts last night and installed them this morning.....so far so good, but we will see =) |
Re: Need help ASAP....issues after maintenance over 600 miles without any CEL.....so I am glad that it taken care of. I think I am gonna get the NTK O2 sensor though.....its starting a idle a "little" rough. Most people probably wouldnt even notice it, but I do, and I dont like it. Further more, she is getting 37 miles to the gallon (which is good but not great) so I am thinking a NTK would get me were I want to be.... Thoughts??? |
Re: Need help ASAP....issues after maintenance It's only rated 36mpg new so, consider yourself lucky. Most people would kill for 37mpg- in any car. lol |
Re: Need help ASAP....issues after maintenance i would still go with ntk, just to fix the roughness. oxygen sensors are way overrated in terms of effect on mpg. when mine went bad, i only got 1-2mpg less than usual. |

DO you think there is a chance I would be able to sell the Bosch O2 sensor PN# 13532? The damn thing is $50 bucks new and it only has about 1k miles on it.....any chance I could get $20 for it or something? |
Re: Need help ASAP....issues after maintenance throw it up on ebay someone will buy it |
Re: Need help ASAP....issues after maintenance Hey guys.....just wanted to update you all that the NTK O2 sensor had made a big difference. After all the new parts are in and she has been driving like a champion for the last month, she is back to running at 40 mpg! Is this a brag post? ABSOLUTELY! Could not have done it without you guys.....thanks for all your help! |
Re: Need help ASAP....issues after maintenance nice glad we were able to get it working. i forgot to mention, it usually takes around 100 miles for all the ecu readiness codes to set before you see the best improvements. |
