"92 SC400, gives me a code 13...it is not the belt or the ECU, so I am going for the ENGINE SPEED SENSOR......I was putting in a new coil and moved a plug that was under the distributor while removing the cover and the engine light came on after that. I went back to check all the wires and plugs and found this grey plug that comes from some type of sensor located on the lower left front side of the engine below the distributor had both wires totally peeled clean...I taped the wires and still get the Code 13.
Is this the Engine Speed Sensor?
The local part places do not even show it in their computers, searched FleaBay and the only speed sensors that they show is transmission and wheels (brakes).
Is there a part number to this sensor?
I am going to get this thing running right or it is going to kill me.
I did visit the Lexus dealer with a print out from Mitchell where it shows this Engine Speed Sensor with a white and a yellow wire, they could not find it and a mechanic that he spoke to had no idea what it was.......he asked me to bring it in to see it and that he would sell me the replacement at cost because he was totally lost with this sensor.
Any ideas ?????

 

Sounds like a cam position sensor.. there are two of them, one for each cam, and there is also a crank position sensor. If the wires are damaged to one of the sensors, its possible its not getting a correct signal.

 

Going to play this one out slowly. Going to check to see if I have anything coming out of this sensor then see if it is getting to the computer. I do not want to be changing out parts until I get to the one that needs to be replaced.
Thanks.

 

Certainly thats the way to go. No need to shotgun it and replace unnecessary parts. I was simply saying that there are two cam sensors and one crank sensor. I would check those out first, and go from there. You said one had damage to the wiring, so id make sure it has continuity, and if it doesnt, replace it.
