![]() TRUST IN NGK NTK: Explore components built by the world leader in the design of spark plugs and oxygen sensors.In order to deliver high-quality spark plugs and oxygen sensors to the automotive community, NGK/NTK has partnered with auto manufacturers to engineer automotive parts that fit both the vehicles of today and of the future RELY ON QUALITY IGNITION COMPONENTS: From their start in 1936 through today, the NTK product line is proof of their dedication to innovation, performance, and quality.Rely on NGK/NTK and their years of engineering expertise to provide you with a high-quality O2 Sensor The porous PTFE filter allows atmospheric oxygen to enter the sensor without permitting water or engine contaminants to seep into the casing. The advanced housing is corrosion resistant and protects the ceramic element against silicone and lead poisoning. ENSURE SMOG TEST COMPLIANCE: The NGK/NTK Oxygen Sensor is designed to adhere to OE standards within incredibly close tolerances.Every Oxygen Sensor undergoes a complex 3-test process to guarantee high quality and durability The sensing element, incorporating the NTK premier technical ceramic material, with integrated heater reaches optimum operating temperature in a matter of seconds for quicker closed-loop activation and reduced cold start emissions. REDUCE EMISSIONS: This NGK/NTK Oxygen Sensor features a protective coating to prevent contamination and has one of the fastest activation times in the industry.(I'll have to clamp the wires while a friend turns the key to on. I might check for voltage in the wires tomorrow, but I'm pretty sure I know what I'll get. I know that there is a relay that provides power to the O2 sensor but it also provides power to the other O2 sensor and a couple of other sensors. This leads me to believe that the problem is in the circuit away from the O2 sensor. This vehicle only has two O2 sensors and I verified that I had in fact replaced the one before the Cat. Googling the code, I've come to realize that the code is specifically for "Oxygen Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)". I went home and double checked everything. I took it to Autozone to have them clear it to no avail. I purchased a Bosch direct fit and had it in without trouble. I had the check engine light come on and Autozone told me it was a P0135 and that I needed a new oxygen sensor. This is basically the same engine as a 1998 honda accord. ![]() Let me know if you have other questions or need help. If you have a diagnostic trouble code indicating an issue with an O2 sensor, let me know what it is and I can direct you better. Please keep in mind, it isn't normal for all of these to go bad at the same time. Disconnect the rear secondary HO2S4P connector (A), then remove the rear secondary HO2S (B). Disconnect the front secondary H02S 4P connector (A), then remove the front secondary HO2S (B).ġ. Pics 4 and 5 correlate with these directions.ġ. Disconnect the rear A/F sensor 6P connector (A), then remove the rear A/F sensor (B). Install the parts in the reverse order of removal.ġ. Disconnect the front A/F sensor 6P connector (A), then remove the A/F sensor (B).Ģ. O2 sensor socket wrench, Snap-on YA8875 or SWR2, or equivalent, commercially availableġ. The first set of directions and pictures 2 and 3 show how to replace sensor 1 for both the front and rear banks. Here are the directions specific to your vehicle. Here is a link that shows how one is replaced: Each bank of the engine (there are two banks) has two sensors. You have two upstream and two down stream.
