2016年10月16日 · I read the codes with my AP and found p0031 and p0037. I read around on forums about my front and rear o2 sensors and a lot of people said their o2 sensors were faulty and if you weren't able to reset the codes you might have to replace your o2 sensor

2020年6月30日 · With P0037, the O2 sensor is informing you that the heater circuit resistance is lower than the normal operating range. This code will often appear with P0171. It indicates that the WRX has a lean condition. If these are the only two codes present, fixing what is causing P0037 will more than likely clear the P0171. Subaru WRX: P0037 Symptoms

2008年2月28日 · P0037 is REAR O2 SENSOR HEATER CONTROL CIRCUIT LOW (BANK 1 SENSOR 2) The heater element of the sensor could be toast or it could be shorted to ground if your wires were somehow burnt. Either way replacing the sensor with the attached pigtail / wire harness will fix your issue.

2024年3月23日 · What are the potential causes of OBDII code P0037 on a Subaru indicating a HO2S12 heater control circuit low? Possible causes include a faulty oxygen sensor, damaged wiring, a blown fuse, or a problem with the ECM (engine control module).

2008年1月19日 · Detect open or short circuit of rear oxygen sensor heater. output terminal voltage at OFF is the battery voltage. Judge NG when the terminal voltage remains to be Low. Basically, one of the two wires for your rear O2 sensor are either shorted to ground or open....

2020年6月14日 · I Fixed The P0031 And P0037 Code On My Subaru WRX

2009年4月4日 · You described the exact same problem im having right now with my 2011 wrx sedan. Just installed a turboback 3 weeks ago... and a few days ago threw p0031 and p0037. Can runs like dog crap... fuel economy is terrible. Jacked up the car yesterday and found frayed wires on the rear O2. Blowing fuses as well. Ordered a new front O2 sensor from Rock ...

2007年3月24日 · There are 3 ways to get rid of it, electrical, mechanical and ECU reflash. 1. The electrical fix is a resistor and capacitor spliced into the existing o2 wiring, either you can make one using a 1uF tantalum bead capacitor and a 1MOhm resistor (diagram is on scoobymods) or buy one like the pony express MIL eliminator. 2.

2007年11月5日 · I have an aftermarket MAF sensor on my 02 wrx. I'm not sure what type of MAF is on the car. I purchased the car with the sensor already installed. Could this throw a cel of P0037 too? If not the MAF, where is the sensor that is throwing this code? From what I found on research this would be the Air/fuel sensor and not the actual "O2 sensor".
