2004 Jeep Grand Cherokee Limited BODY & ACCESSORIES Speed Control

Download 1. Disconnect vacuum hose at speed control servo and install a vacuum gauge into the disconnected hose. 2. Start engine and observe gauge at idle. Vacuum gauge should read at least ten inches of mercury. 3. If vacuum is less than ten inches of mercury, determine source of leak. Check vacuum line to engine for leaks. Also check actual engine intake manifold vacuum. If manifold vacuum does not meet this requirement, check for poor engine performance and repair as necessary. 4. If vacuum line to engine is not leaking, check for leak at vacuum reservoir. To locate and gain access to reservoir, refer to Vacuum Reservoir REMOVAL / INSTALLATION . Disconnect vacuum line at reservoir and connect a hand-operated vacuum pump to reservoir fitting. Apply vacuum. Reservoir vacuum should not bleed off. If vacuum is being lost, replace reservoir. 5. Verify operation of one-way check valve and check it for leaks.… Read More

2003 BMW 325I Sport Wagon Check engine light on and fault codes stored

Download 2002 BMW 325I 2.5L 2003 BMW 325I Sport Wagon 2.5L, Eng Des M54, USA Customer Concern: Check engine light on and fault codes stored. Vehicle running normally. Tests/Procedures: 1. Based upon stored fault codes for secondary air system, there is little or no flow of secondary air into engine. Typical causes for this issue are failed secondary air pumps and/or secondary air check valves. Secondary air pump should operate under normal circumstances when vehicle is first started to perform system test. Pump will normally be heard running when standing in front right corner of vehicle. 2. The secondary air pump is located in the right front of engine compartment. A secondary air pump relay located in the glove box is controlled by the engine control module and sends power to the secondary air pump. 3. Air pump can be disconnected and supplied with power and ground at pump to verify operation is possible.… Read More

DTC P0442 Evaporative Emission (EVAP) System Small Leak Detected

Download DTC P0442 Evaporative Emission (EVAP) System Small Leak Detected Refer to Engine Controls Routing Diagram, EVAP Control System Overview . System Description This DTC tests the evaporative emission (EVAP) system for a small leak. The control module monitors the fuel tank pressure (FTP) sensor signal to determine the vacuum decay rate. At an appropriate time, the control module turns the EVAP canister purge valve ON and the EVAP vent valve ON. This allows the engine to draw a vacuum on the EVAP system. At a calibrated time, or vacuum level, the control module turns the EVAP canister purge valve OFF, sealing the system, and monitors the FTP sensor input in order to determine the EVAP system vacuum decay. If the control module detects a leak larger than a calibrated amount, this DTC sets. The following table illustrates the relationship between the ON and OFF states, and the Open or Closed states of the EVAP canister purge and vent valves.… Read More

1984-1995 Honda Civic/CRX Positive Crankcase Ventilation (PCV) System

Download SERVICE Positive Crankcase Ventilation (PCV) Valve For PCV valve removal, refer to Routine Maintenance of this information. 1. Locate the PCV valve. With the engine running at idle, use pliers to pinch the PCV hose between the valve and the intake manifold. It should be possible to hear the spring loaded valve click shut. 2. If no click is heard, remove the valve from the engine but leave it connected to the intake manifold. A hissing sound should be heard and vacuum should be felt at the valve inlet. 3. If no vacuum is felt, remove the valve from the intake manifold hose. The engine should stall or almost stall. This will indicate a stuck valve or clogged hose. Check the breather hose for clogging or leaks and replace any defective parts. Exhaust Gas Recirculation (EGR) System FUEL INJECTED ENGINES General Information See Figure 3 The Exhaust Gas Recirculation (EGR) system is used to control emissions measured at the tailpipe.… Read More
