P2820 on Acura
Pressure Control Solenoid "J" Performance or Stuck Off
P2820 on Acura vehicles indicates pressure control solenoid "j" performance or stuck off. Au7o has documented this code across 1 Acura model — most commonly on MDX. This code means the transmission control module determined that pressure control solenoid "J" is not responding as commanded or is stuck in the off position. These solenoids regulate the hydraulic pressure that applies the transmission's clutches and bands during shifts. When this solenoid is stuck or underperforming, the result is typically harsh or incorrect shifting, slipping, or limp mode. It can stem from a mechanical sticking of the solenoid/valve as well as fluid or electrical issues.
Common Causes of P2820
- •Stuck or faulty pressure control solenoid "J"
- •Low or contaminated transmission fluid
- •Debris in the valve body sticking the solenoid
- •Internal valve body wear/fault
- •Wiring or connector problems to the solenoid
- •Faulty transmission control module

Acura MDX(1 issue)
- ZF 9-Speed Transmission Hesitation, Hard Shifts and Stalling (2016-2019 MDX)2016-2019
The ZF 9HP 9-speed automatic introduced on the 2016 MDX suffers from documented hesitation, harsh shifts, lurching, and unexpected downshifts/deceleration. Drivers report the vehicle hesitating from a stop, banging into gear, or briefly losing power. Software miscommunication between TCM, ECM and throttle control is the alleged root cause; a class action was filed alleging Honda knew of the defect from 2015.
