Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
In this video on this truck we've got a code for a malfunctioning knock sensor, so we'll show you. We went underneath, investigated, and found that the wire was broken, so we just went out, got a new connection end and then spliced it back in and set it back up. Now the truck runs with no codes flashing.
Right up here is the sensor I will be replacing. I have a 7/8 inch fitting wrench. Put it up onto the O2 sensor. Then I'm going to use another wrench. Put it on there. That will give me some extra leverage. The exhaust is hot still. That will hopefully help me get some more . help it break free. It's not breaking free the easy way.
Right up in here, we can see this is our knock sensor. You can see the problem right off the bat. There is no wire. This is the insulation. Pull the wire out. There's the wire. The wire is broken. We'll just remove this. Squeeze here with both fingers. That comes off.
We've got a new connection. We're going to splice it on. We've got our wire stripped just about 1/4 of an inch off. Insert that into our splice. Take our crimping pliers and put a nice crimp in both the connector as well as the insulation. That's nice and secure. Here's my wire here. We've stripped off the same thing on the end. We'll insert that into our splice. This wire insulation actually really shouldn't be wired high on there. It causes too much stress on this wire, and that's why it broke in the first place. So, we'll wrap that back around. We'll just fast forward here a little bit as we just put that insulation onto the new wire. Tape it and plug it back in. Just position that insulation so it protects from chafing.

My engine runs much better on cold start
VERY GOOD HIGH QUALITY Product at the BEST PRICE!
Great
exactly what I needed and a great price and I received it very quickly I was super satisfied with the business it was very professional and done accordingly
Exactly what I needed exactly what I ordered showed up in a timely fashion very happy
Went right on so far so good. Probably better than the stock OEM
sensor worked as it should. saved me half what local parts stores price.
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.
This will work perfect. Well packaged came in one piece.
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.
