Circuit Description

WARNING: This page is about a different car, the 2004 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.

The throttle pressure that is applied to the primary regulator valve modulates the line pressure causing the line pressure solenoid valve to precisely modulate and create line pressure according to throttle position or engine load. This modulation action controls the line pressure which in turn provides smoother shifts between gears.

When the PCM receives the throttle position opening angle, the PCM controls the line pressure by sending a predetermined duty cycle to the solenoid valve

The line pressure solenoid valve controls the transaxle line pressure for smooth transaxle operation based on signals from the Throttle Position sensor and the VSS.

When the PCM detects a continuous open or short to ground in the line pressure solenoid circuit, then DTC P2716 sets.

DTC P2716 is a type B DTC.
