Bad or wrong sensor for my engine.

February 19, 2017
I received either a bad or wrong sensor for my 454. I went to the local NAPA and got one that works. A total waste of $25.00.. lesson learned.... I won't be using 1A auto parts again nor will I recommend them!

while removing old knock sensor, the head stripped right off, tryed vice grips to remove the stripped bolt and theres no sign of it coming out. with the new sensor from 1aauto i had to locate a new hole in the block to secure it in. after doing so, the obd1 code 43 was still showing. faulty sensor? bad location on block? not sure, what i do know is i have both obd1 code 42 and 43, which points to the EST. time to search the web for information on that.

I purchased this knock sensor on the phone. Made a comment about two being listed and they assured me this was the correct one. I installed the sensor and the truck still threw codes. I did some research and found that this was the wrong part for my application. The black sensor is for a manual transmission and the white sensor is for a 4l80e auto. I bought the right sensor local and it solved the problem as expected. The service was good and they were helpful in getting the cost of the part refunded. They were all friendly and great to deal with if the knowledge was there it would have been a great transaction. I will try them again at some point but will be sure to do my research before ordering.
