I have a grand vitara with a 2.5 v6. it quit running while driving.a scanner tells me my problem is a camshaft position sensor circuit malfunction.i removed the wire clip from the CMP and tested voltage...
I have one too. 04
ok CMP is bad, the ECU knows so. it will not lie.
the ECU monitors this sensor , it generators a fast square w
using DC meters is FAIL.
we use a scope, scopes see AC signals as they really are.
The levels will be wrong or the signal cuts out,
My scope cost me $200 , want to spend that much just to prove the ECU wrong?
A meter (10,000 makes) will show and average , or other ways.
(true rms, etc, or junk meters aplenty)
a meter is going to show different voltages for different duty cycles and frequencies, some meters are so slow they see nothing. (lies) That meter is for DC, only. or if fancy you can , min max.
I guess its no Fluke meter...
why do that.?
It can only be 3 things, Ill assume the fuses are good.
it does use 12v.
the CMP is bad, just as the ecu told you.
the eCU sees 1 pulse missing out of 8 (or so) and BANG, DTC failure. and CMP love to fail hot.
some leak oil and drown that is the oil shorts the electronics.
the wires are bad,. at either end.
the ECU is bad, (id bet $1000 its not)
the CMP, wires and ECU.
ECU dont lie about CMP, not ever.
its a key stone device, like a pace maker in a heart patient.
id bet, bad cmp.
find a used one. but they do fail on suzuki's hot.
many have horrid heat soak issues, an the oil leak deal.
i think SMP sells them and cardone 1 sells rebuilts.
ever seen, rockauto D O T C O M.
