I bought aftermarket NTK sensors and have read how aftermarket ones have been unsuccessful with other people. If I get Bosch or Acdelco will this fix issue.? for the guys who have done this or know anything i should know please please help as my car needs an emission test ASAP.
Thanks for reading
Many owners on here have had success with aftermarket sensors, even e-bay cheapies. I believe the NTK is direct fit, not the kind you have to splice the wires, right? Are you sure the connectors are fully seated? Reversed front/back? Right part numbers? What is happening to you doesn't make sense.
I replaced my with oem, since this time, no problem and I only replace two front, two after cat. still original that have 161000 miles. I know they experience, but I found ebay seller who sold me two new for $50 each oem Bosch sensors, part number was different because Bosch changed numbers. But u can call dealer and find correct number. Now my sensors was originally with out connector, thats whats save u money, I just cut mine original from bad sensor and weld wires to new sensors, dont use quick wire connector, u need to weld wires togather and just tape them, then cover wires with temp. resistant wrap that on sensors. Go to autozone, order 1 front Bosch for $99.99, see if codec for bank 1 will clear. Go to my facebook "Ivan Rossinskiy" im in usa. Go to my albums, "My baby's!!! U will find pictures of sensor
I will try and see if the connectors are in proper seated even though they were installed by a mechanic and check for dirt. But ya they are direct fit. I cut one of the old ones in half and they have same amount of wires. (have read aftermarket have less wires ) the parts store around me in Ontario only can get NTK and there price is 145 per. So i went with Rockautos NTK and they sent wrong ones(i always double check before installing) first but they sent correct ones after i called to inform and we installed and only those codes. What else could be causing this? MAF? Getting absolutely no other codes no history or pending codes just current
