keep getting a obd1 code 32 (egr fault). anyone know what to do with it? clean the valve? clean out the passage in the intake? all the vacuum lines and electrical look ok. car is a '93 new yorker salon w/3.3ltr. ultradrive. and seems to run ok. anyone have some experience they will share? thanx.

 

I have a 1996 Chrysler Concorde 3.5 L engine with error code P0401 - hence faulty EGR valve. If I install a vacuum gauge into the Electronic EGR Transducer (EET) vacuum line, and start the engine, what would be the proper amount of vacuum pressure that the EET should be receiving?

 

Error Code P0401- Exhaust Gas Recirculation flow insufficient Detected.

 

My car is an LXi 1996 Chrysler Concorde with 3.5 L V6 OHC 24-valve engine.

The Haynes Repair Manual says the 3.5 L engine should have 39 psi with the regulator vacuum hose attached, and 48 psi with the regulator vacuum hose disconnected. The fuel injector resistance should be 12.4 ohms.

And, the Haynes Repair manual says if I start the engine and apply 5 in-HG of vacuum to the EGR valve, with the engine at idle speed, the idle speed should drop considerably or even stall as the vacuum is applied.

Now, if I install a vacuum gauge into the Electronic EGR Transducer (EET) vacuum line, and start the engine, what would be the proper amount of vacuum pressure the EET should be receiving?


Should it be less than 5 in-HG of vacuum pressure, or should it be 15 to 20 in-HG, or should it be 25 inches of mercury?
