So my maxima has been doing great for quite a while..Probably been two years or so since anything has gone astray on the Max But i had an issue today..


She went into limp mode and poured out 5 DTC's.
Here they are..

po505 Idle Control System
po325 bank #1 knock Sensor
po130 o2 sensor bank #1 - Sensor #1
po750 Shift Solenoid
p1760 Over run clutch solenoid valve circuit

Here what happened when she took a crap.


. . . .Was driving at a cruising speed and slowed down at a stoplight, Light turns green...Start driving again.Revs all the way to 3500 rpm before shifting (jerking) into 2nd, Its an auto as well...Just an fyi.

I turn off the car, restart her..OD is blinking at me..She is fine for about 2 mins and back to high revving and hardly any movement what so ever..

A little history, The max was in an accident and I rebuilt/replaced a lot of things while she was down....So I know the ICV is clean and should be fine..Never changed the knock sensor.Im guessing 0325 DTC is the one under the plenum.

My initial guess would be that the knock is the main fault of this recent issue and the rest are just along for the ride, Any help would be great. =]

 

Any input guys ?

 

My bet is on these two. Something wrong in the tranny.

po750 Shift Solenoid
p1760 Over run clutch solenoid valve circuit

I dont think they other three would have anything to do with high reving.

Dont know much about the tranny codes. Get the FSM and read up on it.

 

U can try cleaning the o2. If that dont work u will need to replace. shift solenoids is tranny issues man. might need to replace the tranny.

 

Knock sensor wont cause you problems. I'm guessing over revving caused the engine codes. How old is the fluid, is it burned. Fix the trans issue and clear codes. Go from there.
