Vehicle make/model = 2000 pontiac bonneville ssei
Mileage = 125000
Engine size = 3.8
codes = p0102
tech = jk
question = the fist code was bank 1 running to lean changed pluges
wires now this code comes up mass circut voltage low what could that be
JK:
You could have a vacuum leak. Suggest checking for that first.Next, check all fuses,
then check the wires at the MAF sensor connector. Sometimes they break inside the
colored insulation. Pull slightly on each wire at the connector. If a wire is broken, then
the insulation will stretch. This will give the P0102, which may also have given the lean
code.
