Grand Caravan V6-3.3L VIN R (2005)
Top Dead Center (TDC) does not occur when notches on the camshaft sprocket pass below the sensor. TDC occurs after the camshaft pulse (or pulses)
and after the 4 crankshaft pulses associated with the particular cylinder. The arrows and cylinder call outs on represent which cylinder the flat spot and
notches identify, they do not indicate TDC position.
