ok, I have a stock D16Z6 engine into my 93 Del Sol si. And since I bought it my check engine light is ON with the code 41 (heated oxygen sensor heater). My stock ECU is P28, but what I have is P0A ECU for 94-95 Accord EX (F22B1 engine). I tried to find P28 but I can't find any here. I have replaced my O2 sensor many times and I do reset my ECU but still the code 41 is still ON. And I feel my car is running rich because my CO is high at idle, black smoke when I Rev over 5,000 RM and my gas mileage is around 25 m/g. Can anybody help me to fix this 41 code? I have tried to check the wiring of my o2 sensor to the ECU and i think everything is alright. Anybody can help? Thanks a lot

 

Bump anyone???!!! PLS

 

easy fix put in the right ECU. Not sure why you are putting in mult O2 sensors and havent got yourself the right ECU

 

As what I have said, I CAN'T find P28 ECU in here. I have searched everywhere! OK, is there any other ECU can replace P28??? a similar one?

 

Bump! anyone?

 

Where are you located? That info may help... especially if you are not from the US.

One word.....eBay

Again still a little lost took under 30 seconds to find you over 224 listings granted some of them are for chips but there are at least 10 ECUs on the first half of the page. Mabe your only problem is that you are not in the US but I am sure that you could get it shipped

Thanks guys. I'm living in UAE, hard to find P28 ecu here. Is it work the try to buy P28 ecu? maybe isn't the ecu that causing the problem. I have tried using P84 ECU also but no luck, still the code 41 appearing on my dash. Is there any ECU that is very close to P28 ECU? I mean one that I can use instead of P28 which can work with my o2 sensor without any problems. If there is any, I'll try to look around in here before buying P28 from ebay. I so sick from the code 41, I want to get rid of it. Thanks!

 

Bump guys... I have found P30 ecu, can I use it instead of P28? I can't find any P28. Pls help!

 

BUMP...

 

I have find P30, P08 and P2J ECU. Which one is better to use instead of the P28? I need to clear Code 41, use my VTEC and get better mileage. Thanks!

 

You can purchase a P28 or equivalent from xenocron and get one with a zif socket to interchange chips and lean the car out to eliminate the CEL.
