Mitsubishi Gallant Codes Po765 po760

Ask Us A Question HERE

Mitsubishi Gallant Anti-lock light was on the dash then a couple days later I was on the freeway doing 65 miles per hour my car dropped down to 40 miles per hour and the RPM’s went up high but my car would not accelerate.

When I pulled over to put it in park I tried to move It again by putting it in drive, my Mitsubishi Gallant would not budge no matter what gear i was in. My transmission fluid was full. Someone told me it has to do with solenoids. Please help.

ANSWER: Yes, the codes Po765 po760 are for a problem with the transmission shift solenoids. You need to have them diagnosed. It could be a wiring problem going to the solenoids, but most likely just a faulty part.

Shift solenoids do just what they are called- control the transmission shifting. The ABS light may be related also. When the computer sees a problem in the transmission, it will disable the antilock brakes- depending on what the fault is.


Nissan Frontier EVAP Vent Valve

Keep getting a Vehicle specific DTC that vent control valve is not functioning, valve is brand new in working condition, ran new hot wire to valve directly from fuse block ran new neg wire to valve to within 3 feet from ECM, is the problem with the ECM?

ANSWER: First of all, you wired the valve incorrectly. Your emissions EVAP vent valve now has a constant power and ground. So it is always activated. That is incorrect. The valve needs to open and close when the ECM needs it to do those functions. The ECM opens and closes it depending on other things- engine run time, coolant temp, engine idle or higher RPM, etc. The ECM controls the ground side. Without having a scanner looking at the current requested state of the valve and is it open or closed it is hard to say what the problem is. If the emissions evap vent is actually opening and closing as it should, then there may be a leak in the EVAP system. The computer looks for the pressure to go up when the valve is requested closed. If pressure does not rise, it sees that as a vent valve problem.
