EGR Bypass Valve Check

Comp. Loc:

TOOL REQUIRED
J 39200 Digital Multimeter

REMOVE OR DISCONNECT
1. Three vacuum hoses from Exhaust Gas Recirculation (EGR) Bypass valve.
2. EGR Bypass valve electrical connector.

Measure
^ Resistance of the EGR Bypass valve terminals (valve side). Resistance should be 37 - 44 ohms at 20°C (68°F). If resistance is not within specification, replace EGR Bypass valve.
^ Resistance between terminal (valve side) and body. DVM should read 1 M ohm or higher. If resistance is not within specification, replace EGR Bypass valve.

INSTALL OR CONNECT
1. EGR Bypass valve electrical connector.
2. Three vacuum hoses to EGR Bypass valve.
