Check Engine Light Codes Discussion

[B.R.03EX]

Is the sound coming from your power steering pump? If so, mine has the same sound. I only hear it when its cold out. Check your fluid level. If its low, top it off and check your send and return lines coming from the reservoir for leaking.

-.- so today i turned on my car, and outta the blue my airbag light came on...no CEL... checked anyway, got the same code from before and now a P0216... but nothing about airbag...

[timot_one]

Maybe it's a fluke?    Sometimes it's an issue with the seatbelt buckle.  So you always have a P0216 code, or is that new?

[Armyguy239]

new w/o cel on

[Mike]

Did the code reader say it was actually a code or did it way that the code was pending? Your CEL could be on its way to coming on the code is pending earlier in the engine cycle than the point where the CEL actually comes on this of course is to try to avoid a CEL for a sensor sending a bad signal once or twice.

[Armyguy239]

no it was a code...give me few minutes and i'll post what it says

*edit* never mind, it erased, no codes..... stil have airbag light on

Bump.

My car is a 2005 Sedan LX, I4, 5-speed Auto(tragic).  I ran the OBDII scan and received this code "P0141 :: Definition : Secondary HO2S heater malfunction (HO2S BANK 1, SENSOR 2)".

I read this entire thread, searched on hondapartscheap.com and contacted my local stealership.  I still am confused on what part to purchase.  When I do a part search on hondapartscheap.com, I find the following:

Without using the VIN and entering a KA5AT engine:
36532-RAA-A02 SENSOR, OXYGEN (DENSO)
$67.85
** When giving the local stealership my VIN, they also provided this part number.  It didn't match the part number below (i.e. by searching online using the VIN), so that is one of main reasons of this confusion. **

With using the VIN (same as entering a KL5AT engine:
36532-RAD-L12 SENSOR, OXYGEN
$208.93

There is a significant difference in price.  So here are my questions:
1. Is there a significant difference between the KA5AT and KL5AT engines?  If so, what are the differences?
2. Is there an actual difference between the two parts?  Could I get the more inexpensive one?  Would the installation and performance/operation of the inexpensive part match that of the more expensive part?
3. Should I bite the bullet and purchase the expensive one as recommended?
4. Are there any alternative?

Thanks in advance all!!

there could be a number of reasons for why you received that code other than a bad sensor, what exhaust mods do you have?

[HEcreated487]

^^ Everthing is STOCK (intake, IM, headers, exhaust).  LOL.  I read that there is a slight loss in MPG if the O2 sensor is bad.  The weird part is that I did not decrease in MPG after running a week or so with the CEL on (yeah, not a great thing to do, but am still doing the research).

[CrackerTeg]

When I got that code, I replaced the sensor. Problem solved. The sensor I picked up was a Bosch from the auto parts store. My car is mostly stock. I think I paid about $70 for my replacement sensor.

The sensor is on the KA code is for cars with out california emissions. Genearlly there is a major difference in sensors for california emissions vehicles to meet the more difficult particle per million regulations.

[HEcreated487]

Thanks for the response guys.  I do not live in Cali, so I do not have to meet emissions requirements, but the car may have been imported from Cali.  If it is indeed the KL engine type designed to meet the strict emissions requirements, would I still need to purchase the $208 KL part?  Again, I am not in CA, so does the KL sensor still apply?  Or if I was to use the $60 KA O2 sensor, would that mess with my ECU since I should be using the KL sensor to match my VIN?  I would much rather spend $60 if the parts are similar and function similarly, but it would be unfortunate if that part did not work...

[Mike]

If you car is indeed a California emissions vehilce your ecu is tuned to run with that set of sensors. I would suggest that you buy the correct part. Also California emissions is not only in California other states have the requirements on certain year vehicles as well its tough to explain but, your car very well could require cali emissions even where you live.

[Mike]

The Bosch part number for the OEM sensor is 15410 15 410 I'm sure you could get it for far less than the dealer price. I think its like 120 on amazon.com

[HEcreated487]

THANKS MIKE!!    I would much rather buy the KL part now since the price is much more reasonable at $120.  I would feel much more confident with the BOSCH #15410 15 410 OEM sensor replacement part, as it should install and operate the same as the Honda #36532-RAD-L12 OEM part.

Amazon is showing it listed as $120 - http://www.amazon.com/36532RADL12-Bosch-Accord-Oxygen-Sensor/dp/B005OFJR14
