Check engine Light - 1/9/2007 12:54:35 AM    jim70   Posts: 7 Score: 0 Joined: 1/9/2007 Status: offline Hi all, My 1997 Aspire up for smog test vand I've had the Check Engine light on for a while,yet it runs sweet.The fault code is P0470 and relates to the Engine exhaust pressure Sensor circuit.Any ideas of what a quick easy fix may be?Only this one fault found.I looked around the EGR valve and noticed a wire with a connector just hanging there directly above the alternator.I cannot seem to find anywhere that it may plug into.Perhaps meant to be hanging and not used??I can't seem to come across any other Aspires out there to compare. Thanks for any help out there.I'm brand new to the forum.  Post #: 1

RE: Check engine Light - 1/9/2007 12:27:23 PM    Hayapower Posts: 1963 Score: 0 Joined: 7/22/2006 Status: offline The EGR Boost Sensor would be the prime suspect.. (Shown in the pic)  DTC's P0470 and P1195 are a malfunction in the exhaust gas recirculation (EGR) boost sensor circuit/sensor... _____________________________ 05 F250 C/C FX4 6.0 1969 Firebird Trans Am 2003 Hayabusa GSXR1300 (in reply to jim70) Post #: 4

The pic I posted earlier is WAY better than the parts department.. They now use alot of generic (poor) pics for most applications.. It looks like, and the listing calls for 'EGR Control' as a combine parts panel.. I'm not familiar really with Aspire, but looks like they only offer (still available)  the complete control panel.. The DPFE sensors for EGR pressure/flow for other MY's/applications or Ford products fail 'quite' a bit.. If  I'm getting the correct info. as to the panel (and it incorporates the EGR boost sensor), it lists for 150.00!! Hard to believe that it wouldn't be sold as a separate part.. Before 'guessing' the part at that cost, the system should be proved out as far a circuit/s.. Unless maybe you can get a used unit from a salvage yard for a test.. _____________________________ 05 F250 C/C FX4 6.0 1969 Firebird Trans Am 2003 Hayabusa GSXR1300 (in reply to jim70) Post #: 8
