Hi

Strange problem happen to me yesterday, actually it's first time I saw this happen.
In the past we did many K swaps for eg and ek civics.

But yesterday after starting tuning the car, I noticed that when the cooling fan is on the car goes too rich, the short trim fuel trim goes fully negative ...

problem fixed , it was not cause of O2 sensor , it was from the new k manager , the 1.2.3.3 version , i just switched back to 1.2.3.2 , clear security , then i uploaded my cal , the car run perfect except the O2 issue, i took the car for a cruise and it runs perfect .

i dont know whats the problem ...

yesterday after racing some cars i had some issues , first cel showed up , it was p1166 and i know its for primary O2 sensor heater .
everything was just fine except the 02 problem.
so, what are the things that related to O2 heater problem ?

anyway, i parked the car until today . i plugged the ...

or u can connect the wideband output to SO2 white/red wire in connector E, ive done this with my PRA ECU in the past with AEM wideband , so u can read the voltage of the SO2 sensor for data logging . it was very useful .

the code showed again, so i tried to know what is the problem and diagnose it .
but still couldn't solve the problem .

will as i said be4 its not a big problem , but its a lil bet annoying .

so this is what happen exactly .

if i start the car for warming , the a/f ratio will work after few second ...

thanx for the answer .
got my problem solved , just replaced the sensor wire connector sensor wire , it was loosin too much .

ill check the wires today, but the code tells me that the primary sensor is not working , nothing about the heater , i had heater cel be4 (heater not working) and i fixed it .

i read somewhere here in the forum that if the heater is down then the a/f sensor will not work correctly or will not work ...

couples days ago i got code P0134 a/f primary sensor not activated detected.
i got this code after i switched from PRA k-pro to PRB k-pro for my CTR.
i can clear this error by clearing the dtc's in k manager or restarting the engine . but some times it shows in the next day after i warm the car ...

the ecu was done at locash racing .
sorry i didnt mention that the ecu was workin fine, thats before the car got an accident , so we swapped everything to ek9 civic , since then we got code 9. even if we tried the ecu on another h22a , we still got code 9 .

hi

will , after the installation is done , the car the ecu through code 9 , Cyl sensor error as i remember , we tried to get rid of it but it still there, so we moved the ecu and installed it in another h22a engine , it throughs the same could,
so my question is , is my ecu is dameged ?
please need ...

thanks for making everything clear :)

hi
actually i did a good search , until now i couldn't found any useful answer
my question is , which one should i get for my car , i want to switch from PRA k-pro to USDM PRB k-pro,i already bought 02-04 RSX-S k-pro , but which sensor should i run , the 02-05 Civic Si O2 sensor part#36531-PND-A11 ...

last couple days i took the car for street tune, i uploaded the 9psi calibration provided by k-pro , first run i got 5 knocks, the afr was around 11.6-11.8. so i aded 2% of fuel and pull 2 degrees, nothing change, again i pulled another 2 degrees, did one run the knock count is increasing from 5 to ...

hi

i got jrsced CTR with 3.2 pulley ,denso ik24, aem 3.5 map sensor and 750inj and i have one question
do the belt slippage has anything to do with knocks ?
cuz i got a mass knock counts after 6500rpm just after the belt slippage, nothing below 6500 and its run 100% perfect with no issues.

for ...
