hi everyone....i have ford explorer 2008 xlt...and i had an issue which is first RSC service now ( roll stability control) and ckeck out by computer and gave me those codes :
p1891
p1867
p1825
c1233
c1155
the machanic said the main problem is pms(the computer of the car) and its expensive .....should i replace it or there is/are other problem regardless pcm..the car doesnt response when the gear is on "D" when i exceed 40km/h

thank you

 

Based on the list of codes, I would not be condemning the PCM or the RSC systems. Your current codes seem to pertain to two systems, the transfer case and the LF wheel speed sensor for the ABS.
