I have a 98 Honda civic and when I drive it the transmission hits late. I ran a scan tool on it and it came up with a lot of codes:
P0108, P0122, P0505, P0325, P0700, P0720, P0730.
Please help thanks.

Hi diazabreuh,

Thank you for the donation.

P0108 = MAP sensor circuit high voltage input.
P0122 = Throttle Position circuit low voltage input.
P0505 = Idle Control malfunction.
P0325 = Knock Sensor circuit malfunction.
P0700 = Any transmission defect. Would come on if any trouble codes for transmission is detected.
P0720 = Defective countershaft speed sensor.
P0730 = Defective shift control system.

Some of these codes are interrelated and the 3 main item would be P0108, P0505 and P0122.

Erase the trouble codes and test if all the codes comes back. Check if the MAP and TPS sensor wire had been mistakenly swapped.
