What any of these databases can teach us is how to interpret long-term fuel trim (LTFT) values. We need the test plan from Identifix or any other troubleshooter test tips if we do not know how to test to see whether the vehicle is running lean. With some scan tools, we can connect to repair databases such as Identifix. Do we have a vehicle that is running lean (exhaust leak at the front oxygen sensor, vacuum leak on MAF vehicles, front oxygen sensor вЂњstuck lean,вЂќ clogged injectors, weak fuel pump, etc.) or do we just have a lean rear sensor (exhaust leak before the rear sensor, rear sensor вЂњstuck lean,вЂќ or mixture adaptation not done with a scan tool)? Since we have a rear oxygen sensor reporting lean, and both a TSB and an Identifix quick hit indicating different causes that might lean out the senor, our first step is to confirm what is going on. Other tools will also help cut down on diagnostic time, including an emissions analyzer, bottle of propane, smoke machine and a scan tool with strong European-enhanced capabilities, just to name a few. First, forget the soapy water! Use a smoke machine. Several tools can help find the problem the easy way. There is also an Identifix quick hit on the problem, indicating if the sensors are not stuck lean that clogged fuel injectors have been known to throw the P2096 as well.

BMW recommends putting a restriction into the tailpipe and spraying soapy water on leak points while letting the car run. The TSB refers to exhaust leaks at weld spots, gaskets, and at the bungs for the oxygen sensors that are relatively common. Thankfully, there is a technical service bulletin (TSB), #M12 01 06, that addresses this problem. After scanning for DTCs, you see you have a P2096, indicating that the rear oxygen sensor is experiencing a long-term lean condition. Small leaks at exhaust system welds and flange gaskets as well as at bungs for O2 sensors are relatively common, and can be found by pressurizing the exhaust system and using soap solution to look for leaks, indicated by bubbles.ДЄ customer brings in a 2005 Mini Cooper complaining the car is not driving well and has a вЂњcheck engineвЂќ light. There is a technical service bulletin, #M12 01 06, that addresses this problem. If the above tests come out okay, try cleaning injectors.Д¬ode P2096 indicates that the rear O2 sensor registers a long-term lean condition.If the front sensors switch normally, and the rears stay low, generally.Test operation of front and rear O2 sensors - the front should switch high and low in the range of 0-1 V, and the rear should maintain a relatively steady 0.5V-0.7V at idle.
