:orangesigh::020: My check engine light came on so I had my car scanned and the codes P0705, P0715, P0720 popped up. I looked those codes up and they are; transmission range sensor malfunction, Input turbine speed sensor malfunction, and output speed sensor circuit malfunction. What could have caused all these sensors to go out, all of a sudden? Could it be relays that are out and need to be replaced? Where is the output speed sensor circuit and the transmission range sensor?

did you do a manual transmission swap recently? 01galant01 gets those codes, and i get p0705 after putting in the solenoids

No. No transmission swap. I recently installed a stereo and sliced up a few wires. My speedometer was out for a minute. I just got the wires fixed and my speedometer started working again. But now the scan is showing all these codes. I know that while the speedometer wasn't working a relay would make a clicking noise. I'm sure that was due to a short circuit. But now that there's no short circuit Im guessing that relays are going to be the cause of all these electrical issues I'm currently encountering.

Try swapping relays you know to work.

I did. I moved some around. I even had extra relays that I got from a salvage yard and no luck. But then again, those relays may have been non-functional too.

I noticed a lack in power too!

Lack in power as in voltage, or driving?

If you have a lack of power with the driving aspect, recheck the A/T Relay, and the fuse that feeds the relay/s power. You may also have inadvertently damaged other wires...but given what wires these are for 3 seperate codes/sensors on the transmission I would start looking at the relay and fuse.

Sorry it took me so long, I got it all figured out. One of the fuses was placed in a spot where there was not supposed to be a fuse and where there was supposed to be a fuse, there was not one. My bad!!!!! LOL! I didn't pay attention to where I was supposed to have replaced that fuse due to spaces between fuses in the interior fuse box. Ooopppsssss!!!!!!!!!!!!!!!
