Check engine light came on …auto zone code says Accumulator it’s also leaking oil …or leaking something…
Welcome to the forum…
Care to share the code??
And are you talking about the AC Accumulator or a transmission Accumulator or?? And how/what is it leaking??

Is this a P171X sort of problem? Auto trans fluid pressure accumulator solenoid circuit?
From what I can tell the trans fluid pressure accumulator is part of the engine auto-stop function, for making sure there’s a ready supply of pressurized trans hydraulic fluid ready to go when the engine stops when you are waiting at a stop light, so trans is ready for you to start going again when the light changes. Are you experiencing any problems with the auto-stop/start function?
