1996 Ford F-150 Q&A

1996 Ford F-150 Question: Where is the Bank 1 and Sensor 1 located?

Is bank 1 left or right, and sensor 1 pre-cat? I have a P0133 code. -
Answer 1
It's the bank that has the #1 cylinder, so just follow your #1 wire from your distributor to the number 1 cylinder and there you have it. And, yes it is the pre-cat Oxygen Sensor. -
Answer 2
this is a picture showing the bank 1 location. http://chinasinoy.com/service/bank-1-location-84.html for p0133: The simplest thing to do is to reset the code and see if it comes back. If the code comes back, the problem is more than likely the front Bank 1 oxygen sensor. You will likely wind up replacing it but you should also consider these possible solutions: Check and fix any exhaust leaks Check for wiring problems (shorted, frayed wires) Check the frequency and amplitude of the oxygen sensor (advanced) Check for a deteriorating / contaminated oxygen sensor, replace if necessary Check for inlet air leaks Check the MAF sensor for proper operation -
