if you want to replace the switch its the brown sensor almost under the throttle body and air cleaner hoseMy 2001 MDX has 160000 KM on it. I got faulty 4th Gear Pr. Switch (P 1740 ). And I do not have D5 or D4 engine lights flashing. Any info like DO it yourself / diagrams / location of the switch etc. on this topic is highly appreciated.
Thanks in advance
