Description
The fuel pressure regulator is connected to the fuel rail. The fuel pressure regulator has a vacuum connection to it.
The fuel pressure regulator is used to regulate the fuel pressure in the fuel system.
NOTE :
The 2.4L is the ONLY engine that uses an external fuel pressure regulator.
Operation
The fuel pressure regulator is designed to keep the fuel pressure in the fuel system at a constant pressure. It does
this with a spring-loaded diaphragm that controls a valve. The valve, when opened by excessive pressure in the fuel
lines, uncovers a fuel line that returns excess fuel to the fuel tank. The vacuum connection is there to help reduce
emissions during deceleration. During deceleration, the vacuum connection serves to open the fuel return valve
wider, which reduces pressure in the system and prevents excess hydrocarbon emissions due to less fuel being
injected as a result of the lower pressure in the system.
Removal & Installation
WARNING!
Release fuel system pressure before servicing fuel system components. Service vehicles in well ventilated areas
and avoid ignition sources. Never smoke while servicing the vehicle. This may result in personal injury or death.
1. Release the fuel system pressure (See Fuel Pressure Relief Procedure in Section 04 Fuel Delivery).
2. Disconnect the negative battery cable.

• Harness or
connectors (The
sensor circuit is open
or shorted)
• Transaxle Control

DTC Confirmation Procedure:
Before performing the following procedure, confirm that battery voltage is more than 12 V.
• Turn ignition switch off.
• Connect the X-431 scan tool to the Data Link Connector (DLC) - use the most current software available.
• Turn ignition switch on, with the scan tool, view and erase stored DTCs in the TCM.
• Start the engine and warm it to normal operating temperature.
• With the scan tool, select view DTC and data stream.
• If the DTC is detected, the DTC condition is current. Go to Diagnostic Procedure - Step 1.
• If the DTC is not detected, the DTC condition is intermittent (See Diagnostic Help and Intermittent DTC Trou-
bleshooting in Section 08 Transaxle & Transfer Case for more information).
NOTE :
• If DTCs P0840 and P0710 are present, diagnose and repair them before continuing with this test.
• Using the appropriate diagnostic test tool, you can diagnose the TCM harness while the TCM is still connected.
This will help prevent electrical connector terminal damage.
NOTE :
While performing electrical diagnosis & testing, always refer to the electrical schematics for specific circuit
and component information.
Diagnostic Procedure
