Yes, Nik have right, by your Lang. is Cylinders. Thanks Nik.
Supl. = supplement or assortment, don´t know said in US. What I try to say, if it´s bad - Camshaft speed sensor, you need located side, because you have two sensors who drive both side (V8), but diagnostic some times doesn´t recognized which is bad, so mine was on left side, which controlled engine valve train? cylinders 5-8. So, you have V6, if you have same specs., and be lucky have only bad sensor one side (left like me) you need change Cams. speed sensor left side engine, supl. cyl. 3-6. Good luck
