    DENSO OXYGEN SENSOR Great

    Denso o2 sensors are simply the best I have found direct fit and trouble free. Replace it and forget it for another 100K miles.

                                This is a factory-replacement part for the O2 sensor #1 (pre-cat).
                                Remove rear coilpack for better view and access.
                                Use a 7/8" (or 22mm) crowfoot to install this item.
                                Came complete with small tube of anti-seize compound.
                                Obviously cannot comment on reliability yet - just installed. Original lasted 200K miles; hope this replacement does as well.

                                      With reference to your inquiry on the Denso Oxygen Sensor Direct Fit -part# 234-4650, a knock sensor tells the engine computer when one or more of your engine's cylinders are "knocking", that is, exploding the air/fuel mixture in a way that delivers less power and can be damaging to the engine if prolonged. The computer uses this information to tune the engine so that it doesn't knock. If your knock sensor on Bank #2 is generating a low output voltage (perhaps under 0.5V), then it will trigger a P0332 DTC. This P0332 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0325, P0326, P0327, P0328, P0329, P0330, P0331, P0333, and P0334.

                                      CODE P0155: This code refers to the front Oxygen sensor on Bank 2. The heated circuit in the Oxygen sensor decreases time needed to enter closed loop. As the Oxygen sensor heater reaches operating temperature, the Oxygen sensor responds by switching according to oxygen content of the exhaust surrounding it. The ECM tracks how long it takes for the Oxygen sensor to begin switching. It the ECM determines (based on coolant temperature) that too much time elapsed before the Oxygen sensor began operating properly, it will set P0155., SYMPTOMS: Likely to notice poor fuel economy the illumination of the MIL., CAUSES: A code P0155 may mean that one or more of the following has happened: Oxygen sensor Heater element resistance is high., Internal short or open in the heater element., Oxygen sensor heater circuit wiring high resistance., Open or short to ground in the wiring harness., POSSIBLE DIAGNOSIS: Repair short or open or high resistance in wiring harness or harness connectors., Replace Oxygen sensor.
                                      For compatibility of this part with your vehicle, please provide your vehicle make, model and engine specification.
