Possible causes of OBD code P0780
- Low transmission fluid level - Dirty transmission fluid - Faulty shifting solenoid valve - Shifting solenoid valve harness or connectors - Shifting solenoid valve circuit is open or shorted The Error code is generally activated on detection of the following conditions: The P0780 codes is detected when no rotation change occurs between input (turbine revolution sensor) and output (revolution sensor) and shifting time is long or when shifting ends immediately or when engine revs up unusually during shifting.So check out these points and see if any are all help keep me posted
that is a dash code, right and not a real scan tool.
read the FSM. it all there.
or go to alldata.com (might be there and is for real DTCs )
or google it.
let me guess, the check engine light is glowing driving
and you ignore that?
scan it , and see all errors. and this
fault Code: P0780(4501);
P07xx are tranny errors.
reset the ecu (scan tool button) and pray it dont come back.
A blinking check engine light is a signal that a damaging misfire is occurring in one or more cylinders. Your car is shaking because of the uneven power loss between firing cylinders and those that are misfiring. If you take your car to a major auto parts store, they will read out the stored trouble codes in your car's computer memory--and they'll do it for free. These codes will tell you which cylinders are misfiring and will help you find out why. Do it soon before more engine damage occurs--$$$$.
po780 is a trans hydrolic systen code
could be a shift solinoid gone bad
have an experienced mechanic replace the lock-up controlle solenoid control solenoid valve/shift controlle solenoid valve "A" assembley
and the A\T clutch pressure control solenoid valve "A"/"B" assembley
start with these two parts farily inexpensive if this doesnt solve the problem then the trans needs to be replaced really expensive
both of these parts are located on the out side of the trans
rank my solution
Jason,
-after you change the part you have to reset/clear the code
-this can be done by either:
(1) using the OBD2 code reader that Autozone used OR since option 2 (below) is very quick
(2) disconnecting the battery for about 30 seconds (this will delete
all codes/radio presets/etc) but it will also clear the 'check engine'
code
-this is what I do AFTER i write down my radio station presets :)
-hopefully the new EGR valve resolves your issue after you CLEAR the code
...but that code just means a an insufficient amount of Exhaust Gas
recirculation (pressure difference) used to keep the emissions in check
-if it comes back, then there are a few other fixes to try also
-let me know if you need further assistance
-please remember to rate me `fix-ya`if it works
thanks
A very common late 90's code, P1457 is a failure in one of the evap
system solenoid valves. There are 2 culprits, the Vent Control Valve
& the 2 Way Bypass Valve. So, start working with those and see if you can get the 1457 code off of it.
I also looked around about the 1739 code as well which a transaxle error. However, I've found that there has been more than enough reported cases of problems of the such. Take a look at this link, and do a little reading.
