You don't HAVE to change it, but you'd probably want to if you've got an emissions test coming up. It's also gonna mess with your gas mileage too. I'm not sure if you can clean those things out but they're about $100 to replace.

You will spend an enormous amount of effort to remove a light bulb that will tell you of that AND OTHER problems... but you won't fix the problem itself?

Save yourself time and money. Just get it fixed now. That way you don't take a gas mileage hit, the lightbulb turns off, AND you still get a warning if there is some other problem. It's the best solution.

Need Help!

My car has been fine until I got this code.

72.............P0302.............................. ...............Cylinder 2 misfire

Therefore, I went ahead and changed the spark plugs, spark plug wires, and the distributor rotor/cap. The car got a lot smoother and the CEL stopped coming on.

Then all of sudden today, I get this code.

9...............P1381,P1382....................... .........CYP Sensor

after looking it up, its something about the Cylinder Position (CYP) Sensor
"Defective circuit or unplugged/defective sensor".


I have NO IDEA what to do to fix this problem! The car was sputtering on the freeway and it scared the crap outta me. I made sure that the spark plug wires were tightly pushed in and all..

I might need to mention that I'm overdue for a tune-up, currently at 108k waiting for the tuneup parts to arrive from http://www.hondaautomotiveparts.com/.

ANY HELP WOULD BE MUCH APPRECIATED.

*PLEASE help me if you know anything about this, Im taking a road trip to see my parents and need to leave in a few days*

I knew something would come up eventually in this car, its been too perfect.
VTEC wont engage, or feel like it is engaging at all, so I went and got my codes read from my CEL. The CEL had already been on because the Previous owner put in a non-Honda Catalytic converter.
* 3 Cylinders are misfiring, got the P030X codes for 3 of the them.
* Took my 1 month old spark plugs out and brushed the crap off, put in new ignition wires. Engine still misfires.
* Also got the P0108 code for Man. Absolute Pressure, I have an aftermarket SRI and has worked fine until now.
* P0420 for catalyst efficiency - low bank 1. ?? Could be because its not OEM honda, or it may be clogged.
* I Seafoamed my car about a week ago, I am now kicking myself in the ass. Maybe the foam knocked some grime loose and jammed up my Cat?

ANY help would be great, I need the car running right in the next few days. Also, Ive been driving around [its my daily car] would anyone recommend not doing that? I would love to let it sit until I could fix it but I dont have another car yet. Thanks again - Mat

Hi everyone, my '00 V6's CEL came on today. Let me ask a question first, when you turn the key to "ON", do you read the CEL immediately or does it come on briefly along with the rest of the dash lights then starts the code flashing sequence then turns solid again?

If the above sequence is correct about the light comes on briefly then starts the code flashing, I have 1 short flash which is P0131,P0132 (Primary Heated O2 sensor circuit low/high voltage. Does this mean it isn't getting enough voltage or too much or does this mean the O2 sensor is on the fritz and needs to be replaced.

If the above sequence is wrong, then I have one long flash and one short flash which would be #11 correct? If so, there is no #11 posted.

Thanks,
Derrick (DTB)

The sensor is behind your crank timing gear, if you are planning to change the timing belt, now is the time since you have to take it off anyway to replace the sensor.

I went to autozone and had them check the code for my CEL. It came up as a P1491 which is the EGR valve. However, I don't see the flashing of the CEL that indicates this I don't think according to the list printed here, but maybe I am and not recognizing it. Is this a dealer only install item or a DIY project that can be done. If so, what is all involved in the replacement. Is it just a purchase and replacement type deal. I've read about people drilling. I don't want to drill on my engine myself.

Thanks,
Derrick

Hey derrick, hows everything? I hope things are well with you

back to the topic..I have had a cel code for about 5 months now. I did that jumper thingy and I got a code of 65 which is the secondary o2 sensor.

I did a defouler trick on to the secondary sensor and then I resetted the CEL. I turn the car and it poped back on again.

Now im stuck..is my catalitic converter not working?

My vehicle is a 98 accord 4cyl.

Sorry I did not see this earlier....

What have you done to the car so far?
Anything having to do with your fuel system?
How many miles are on the car?
Have you ever had your O2 sensors replaced?

umm...currently there is a turbo kit.

It has around 129000kms on it (which is around 80000miles).

The O2 has never been replaced...I have a feeling its the sensor. I was quoted around $100cnd for the sensor which is a denso plug and play.

So, basically, I have applied the DEFOULER mod hoping it would solve it..but it didnt. I need to clear this engine light, so that I can take it to emmissions testing and be able to insure the vehicle.

Info on the car:
1998 Honda Accord Coupe EX / 5spd / 4cyl.

Thank you very much for helping me out.. I appriciate it much

Yeah, with the turbo kit I would get your AFR checked out, you can "Burnout" an O2 sensor if you run way too rich, the carbon buildup will cause the senson not to read properly. I was on board with replacing the sensor, I just like to make sure that there is not some outside issue causing them to fail. Hate to see $100 in parts and the time wasted due to another problem.

Thanks for the reply. I really thank you for helping me out.

I do think its the sensor...cuz I was running too rich at the beginning...and it probably did BURN it out...

I guess the only way to do it is to replace it...oh well!!! I have to do it

Thank you again, and I will keep you posted...gotta order the part.

If you are not getting the factory one, be sure to get eaither a denso or bosch replacement, stay away form Standard Motoro Products and Borg Warner, they are $hit.

Hmm...ok.

guess, what...my cel poped up again. So I did that pin thing to check the code and it flashes 5 times, and there are no quicker flashes...it just flashes 5 time..

Im going to look to see what the problem is. \

Ok...according to the first page, 5 means this:

5........ P1128,P1129...........Map sensor circuit low/high voltage

what the heck is that? haha...oh my, I better take the turbo out.

Check all of your ground connections, when you replaced your O2 sensor, you may have jiggled another connection lose.
