Sebring Convertible V6-2.5L SOHC 24 Valve (1996)
Power Steering Pressure Switch: Description and Operation
Fig. 21 Power Steering Pressure Switch
OPERATION
A pressure sensing switch is located on the power steering gear. The switch Fig. 21 provides an input to the PCM during periods of high pump
load and low engine RPM; such as during parking maneuvers.
When power steering pump pressure exceeds 4137 kPa (600 psi), the switch is open. The PCM increases idle air flow through the IAC motor to
prevent engine stalling. When pump pressure is low, the switch is closed.
CIRCUIT OPERATION
The power steering pressure switch opens and closes circuit K10 between the Powertrain Control Module (PCM) and ground. Circuit K10
connects to cavity 45 of the PCM connector.
Circuit Z1 provides a ground for the power steering pressure switch. The ground is terminated at the left strut tower.
