Hondata

i recently installed the DC Sports Race Header with T1R bpipe with stock axleback on my 02 RSX-S with Injen CAI and Kpro.

well, my CEL comes on and thru the Kpro error code it says: 65-2 P0141 Secondary o2 Circuit Heater Circuit Malfunction.

i tried to upload it with both P1167 o2 heater and P0134 o2 sensor response disabled, but it still comes on.

any suggestions?? thanks

If you have no cat or no 2nd o2 then you must disable OBDII.
