Code P2808 Scion Description

The P2808 code for Scion indicates an issue with the Pressure Control Solenoid 'G' performance. The pressure control solenoid is a vital component of the transmission system, responsible for regulating hydraulic pressure within the transmission. When this solenoid malfunctions or operates outside of the specified parameters, it can lead to erratic shifting, harsh gear changes, and overall poor transmission performance. If left unaddressed, this issue can potentially cause further damage to the transmission, leading to costly repairs or even transmission failure.

Tech Notes for P2808 Scion

When a transmission solenoid malfunction, in most cases the problem is not the electrical part of the solenoid; the problem is foreign material obstructing the mechanical function of the solenoid or the flow of the fluid through the transmission valve body. If the transmission fluid is dirty, it's recommended to change the transmission fluid and if possible, remove the transmission pan for further diagnosis. Excessive debris or metal particles on the transmission pan could be an indication that there is a mechanical transmission failure, and that the transmission will need to be rebuilt or replaced.
