codes 42 and 52

suprabahamut · 07-16-2008, 05:02 PM

I just checked today and I got codes 42 and 52. One says vehicle speed, and the other knock sensor. What does the knock sensor look like If it is a wire with a big round rubber shield hook to it, I plugged it back in it was lose near the oil filter. If this is the right one do I need to pull the battery cables off and check it again? And for the vehicle speed sensor will a bad speedometer cable cause it to read like this? I know the speed sensors are for the ABS I just wanted to know if it has any connection. If any one has any clue please respond I need all the help I can get.

That’s the oil pressure sender unit, the knock sensors are HERE on the other side of the block.

Yeah the oil pressure started to work but still went back to the 0. I think I have to hook up something else as well for the oil pressure. I got a replacement motor at tiger japan 8 months ago so I know the oil pressure is stable but still would like the oil pressure gauge to work. As for the knock sensors thank you I am going to check the connections tomorrow. What do you think about the speed sensor?

The connector is broken on the knock sensor so I have to find out if there is a way to fix it. For the vehicle speed sensor, where is it at? and how can I clear this code?
