my cousin has a 99 ek with a jdm type r motor. he was running a chipped p28 but it ran like ****. so he put a jdm type r ecu in it and now he has cel 41. keep in mind he only has his primary 02 sensor connected. does he need to run his secondary o2?

 

41 is primary o2 heater.

he change the primary 02 already and its still doing the same thing. and we reseted the ecu also

 

well if it's not the O2, that it's the WIRES!!

also CEL41 means that it has the problem with voltage...so it's the feedback problem!

Bingo. Check the connections and wires and make sure everything checks out.

 

ok but why didn't the cel go on with the p28.?

does a jdm ecu read a secondary 02?

It has nothing to do with the secondary 02.

41 Primary oxygen sensor heater

 

he had his stock cx harness modified by a shop i guess he better take his car back
