93crank sensor location on a sonoma pickup - Sonoma GMC Cars & Trucks

• Chevrolet C/K( k= 4wd) pickups.
• Chevrolet Silverado?
• Chevrolet Suburban(no)

USA car or not in N.America at all??????????
which one is it, Sierra is a sub model class not a truck actual.
I will guess C1500????? pickup truck? 2wd./
scan the PCM yet, using any OBD2 scan tool for DTC errors?


it is not bad, 99% are not bad so no need to find it.
why not post a problem and not hunts.
the service manual on the car and google searches ends the hunt.



the knock sensor allows the PCM to tune spark timing to use poor grade fuel. and not allow knock and ping. it does that endlessly.
but if say you heard the engine ping, that is a dead EGR

PING (knock or detonation) is caused by poor fuel and crazy high combustion temps.
The EGR system cures it. (and must be cleaned or fails)
some trucks run spec cams that stop PING>
and some use those and a knock sensor..
it is a microphone ,sensor. and if engine bearings pound load

the KS1 sensor lies., to you. (and the PCM)
example rod knock or piston slap noises.


what truck is it,from USA 1998 list

The Cam Sensor is located in the distributor under the rotor cap. And the The crankshaft position sensor is located on the left side of the engine block. -------- This will help.Thanks.Helpmech.
