Official description

Pressure Control Solenoid Current Error in P/R/N

Laymans terms

This code means there's a problem with a part in your car's transmission that helps control pressure. It's like a switch that isn't working right when the car is in park, reverse, or neutral.

Explanation

The P1830 code is triggered when the transmission control module (TCM) detects a current error in the pressure control solenoid while the vehicle is in park, reverse, or neutral.

Technical description
