i have library of factory FSM books here, PDF on all suzuki and tracker up to 2004
all everyone that has P1875 shows DTC P1875 4L Switch Circuit Malfunction (Open)
every one.
but the SPORT can be different as P1 is a factory ONLY code and only a correct matching manual is the truth and sorry I do not have this one manual.
I think you said you had the sport manual. so.... but I forget./
1998 Sidekick 1600/1800/x90 Wiring Diagram Manual - 99512-60A70-33E
1998 Sidekick 1800 Supplementary Service Manual 1800 - 99501-61A70-33E
Are the books I have. The 1800 Supplement - Page 7B1-43 and 7B1-44 P1875 4WD Low switch circuit malfunction
7B1-43 states the difference of more than 10% between trans VSS and Speedo VSS
7B1-44 Troubleshooting the switch. test continuity between E172-18 and ground (disconnected PCM) followed flowchart of tests - ALL GOOD
My tests.
2Hi and 4Hi - it is infinity
4Lo - There is continuity
I purchase and installed NEW 4Lo Switch and performed tests again - SAME
I can scan the pages and upload them to you if need be.
If I have the aftermarket speedo gearbox on the cable - P1875 codes are generated randomlyu
If I remove the aftermarket speedo gearbox on the cable - NO P1875 codes
So I believe the condition I am experiencing is from Page 7B1-43 differences between speed sensors
