The code P0137: O2 Sensor Circuit Low Voltage (Bank 1, Sensor 2) points out a fault in the oxygen sensor located after the catalytic converter, and most likely is caused by issues in the sensor itself, wiring problems, or exhaust leaks. P0137 quick overview Meaning P0137: O2 Sensor Circuit Low Voltage (Bank 1, Sensor 2) Is it serious? Yes, it can lead to poor fuel efficiency, increased emissions, and potential damage to the catalytic converter if not addressed. Possible causes – Faulty oxygen sensor – Wiring or connector issues related to the oxygen sensor – Exhaust leaks, especially between the O2 sensors and the catalytic converter – Faulty Mass Air Flow (MAF) sensor – Use of non-OEM or incompatible oxygen sensors How to diagnose? 1. Read the fault codes using an OBD-II scanner to confirm P0137 and any other related codes. 2. Visually inspect the wiring and connectors associated with the oxygen sensor for any signs of damage, corrosion, or disconnection. 3. Check for any exhaust leaks, especially in the area between the oxygen sensors and the catalytic converter. 4. If the vehicle has multiple banks, consider swapping the O2 sensors between them to see if the fault follows the sensor or stays with the bank. 5. Use a diagnostic tool to monitor the O2 sensor’s voltage. If it’s consistently low, the sensor might be faulty. 6. Force the system to run rich using propane or another method and monitor the O2 sensor’s response. 7. If suspecting a Mass Air Flow (MAF) sensor issue, test with a known good MAF sensor. 8. Always check for any recalls or Technical Service Bulletins (TSBs) related to the O2 sensors or associated systems for the specific vehicle model. make sure you installed, may have to be OEM O2 sensors. check the MAF sensor, the OEM BOSCH piece is not being manufactured anymore as far as I know. if the wiring is coroded any where causing resistence, even the smallest bit, it can cause a volt drop leading to inconsitant voltage. and look for pin hole leaks before the cat. according to. https://www.iamcarhacker.com/fix-p0137/ -
Next year it will be officially 20 years that I’ve been on VS. The last Volvo I owned got destroyed by the careless asshat I let take it home. It was not my car anymore, and I cannot be sad that a 98 V70 T5 Manual is longer on the road. I miss this community, through the passage of time and life many people have moved on and have real lives away from a keyboard. Yet I still come through and plan on adding content again because I am getting another wagon soon, and I hope that I can get traffic back from another platform that I don’t like.

Volvo repair in the dark is fun at 8pm. But I want to get my car back on the road for #fixxfest #fixxfestprep
