old post TRACKER YOU SAID. (IVE OWNED 4)
its not 1995 tracker, its a usa 96
or canada 98 at least.
the 96+ have 2 baros. p1451 p1 MEANS SUZUKI FACTOR ONLY CODE. (NOT FED)
one is the EGR baro for testinG only it (usa laws)
and the one hidden inside eCU for alitude. readings
had one 96 that spiders got inside it and made nest.
wish you posted true year, sad that.
years match books and facts by year/
ill now teach you, how to use said book
the free 1996 book posted 100s of times here
10,00o hits i google.
now what page. easy diagnostics (PAGE 31)
IT COMPARES THE KEY ON PRESSURE FROM BOTH SENSOR AND IF WRONG,ASSUMES HE ECU SIDE IS BAD
ID NOT BELIEVE THIS.
i mean on or the other can be bad, (its a comparison see?)
i pull the top of intake maniffold MDP baro senors
clean it good with CRC MAF cleaner(safe)
then put it back
push reset on scan tool and drive
if P1451 returns'
open ECU lid, and clean that BARO sensor there
whats there cant guess, but has some junk there, gunk, webs
water, what ever, there.
the book says replace ecu that is $400 at CARDONe.
This is a hard one, only
i have a photo
bottom near center, see baro with gaping hole in it>?
fixed mine, (im an ecu fixer, retired)
and fired all spider gangs in my garage. LOL
