Bmw E90 Oxygen Sensor Heater
BMW E90/E92 O2 Sensor Heater Fuse Access This video is a complete, step-by-step guide on how to locate and replace the oxygen sensor heater fuse in a BMW 3 Series (E90, E91, E92, E93). Figure 5 Using an oxygen sensor socket, remove oxygen sensor from exhaust manifold. Lightly coat new oxygen sensor thread with anti-seize compound.
Install new oxygen sensor and tighten to 50Nm (37 ft-lb). Then reroute wiring harness and connect electrical connector. Repeat if replacing both sensors.
Then reassemble engine covers and clear any engine fault codes using a BMW scan tool.

Greetings, and thanks for checking out this post.
I have an 07 328xi with codes calling the heater circuit for all 4 o2 sensors. I have replaced them and what I have found is a blown fuse in the DME fuse cluster in the white box under the hood, which I have since discovered is for the heater circuit for them. The fuse immediately blows when replaced.
Has anyone found a pinch point or area. If you're getting check engine codes like P0031, P0037, P0051, or P0057 on your BMW, the issue may be a blown oxygen sensor fuse - not the sensor itself. In this video, we'll show you how to quickly diagnose and fix a faulty O2 sensor fuse on common E-Chassis models like the E90, E92, E60, E82, and more.
Save money by avoiding unnecessary sensor replacements and get your engine running. A common source of check engine lights is a failed or failing oxygen sensor. When the O2 sensor can't register oxygen content before and after your catalytic converter, it doesn't know what to do with the fuel mixture and will default to run rich.
Replace old failing oxygen sensors with OEM O2 sensors or quality aftermarket O2 sensors if you're looking to save a few bucks. « Previous Thread Next Thread O2 Heater circuit trouble. DIY guide to replacing oxygen O2 sensors to fix rough idle and limp mode issues in your vehicle.
First post on this forum for me. Working on a 2007 328i e90 with n52 engine. Car came in with a bunch of PCV related issues which I fixed.
However, still have a code for oxygen sensor B1S1 heater circuit (P0135/002CA6). Tried swapping the sensors, and the code followed to bank 2 with the sensor. Every new BMW, and all BMW cars made from 1980 on, have an oxygen sensor, often called an "O2 sensor".
The oxygen sensor is part of your BMW's emissions control system and feeds data to BMW engine management computer. The oxygen sensor is positioned in the exhaust pipe and can detect rich and lean mixtures. The goal of the oxygen sensor is to help the engine run as efficiently as possible and.
