Hello. I am having sensor problems with my 2002 wrx. It is currently giving me the following codes.
P0037 ho2s ½ heater ckt low
p0031 ho2s 1/1 heater ckt low
p1131 manufacturer specific dtc
I have replaced the sensors before but iv been reading about alot of failures using the Bosch 15730 sensors. I am also not sure which code is for which sensor. There is one behind the front right wheel and one in the exhause pipe under the passenger side of the car. Which sensor brand do you recommend? Also what kind of sensors are they? wideband or regular o2 sensors?
Thank You very much
