Hey guys, My truck is a 1996 Nissan Truck IMAGE. All O2 sensors are basically the same, with some being heated or others providing multiple signal lines. I have replaced the mass air sensor and the sensor in the charcoal canister. Was wondering if anybody had any tips on how to remove the downstream O2 sensor. Not so with the faulty one. Unplug the old O2 sensor. 1 On August 4th, 2007, steven said:. It is considered generic because it applies to all makes and models of vehicles (1996-newer), although specific repair steps may be slightly different depending on the model. The problem: Check Engine light came on indicating "fuel mixture too lean", then about a day later the car started sputtering at low speeds. Often enough, the only sign of the problem at all is the service engine soon light being on. 3 Sensor Placement Optimum bung placement will vary from application to application, but using the guideline below will ensure the longest sensor life with the most accurate readings. The heated oxygen sensor 1 has a closed-end tube made of ceramic zirconia. I have bee. P2251 - O2 Sensor Reference Circuit Continuity (Bank 1 Sensor 1) P2251 - Oxygen Sensor before catalytic converter, electrical: Open Circuit, virtual ground P2270 - O2 Sensor Signal Stuck Lean (Bank 1 Sensor 2) P2271 - O2 Sensor Signal Stuck Rich (Bank 1 Sensor 2) P2400 - DMTL Activation Control Circuit Open. But before the O2 sensor can produce a voltage output signal, it must be hot (approx. I'm about to take my truck to the shop tomorrow and dump 60$ for them to remove this O2 sensor. Replacing an aging O2 sensor that has become sluggish can restore peak fuel efficiency, minimize exhaust emissions and prolong the life of the converter. im trying to save some $ , and have to take it to a shop. What does that mean? This is a generic powertrain code, which means it covers all OBD-II equipped vehicles, 1996-newer.
