RE: Code P1857
Probably doesn't get you much further forward but here's a breakdown of the characters within the codes for you
Jim
The first alpha character identifies the system generating the code P = Powertrain
B = Body
C = Chassis
U = Undefined
The second digit says if the code is generic - same for all OBD-II systems - or manufacturer specific
0 = Generic (zero)
1 = Enhanced (manufacturer specific)
The third digit is sub-system type for that code
1 = Emission Management (Fuel or Air)
2 = Injector Circuit (Fuel or Air)
3 = Ignition or Misfire
4 = Emission Control
5 = Vehicle Speed & Idle Control
6 = Computer & Output Circuit
7 = Transmission
8 = Transmission
9 = Reserved
0 = Reserved
