Chrysler Town & Country Emission Repairs

Finally got my 2 Chrysler mini-vans to smog the other day. Both of the cars had vacuum hoses that were cracked and leaking causing the p0172 code to set(Fuel trim too rich). The hoses that were cracked were on the intake manifold side of the purge canister solenoid(on the passenger side of the car).

On the 1997 the 2 inch hose that connects the 2 hard hoses(just above the fan belt) that connect the purge solenoid(on the radiator hanger) to the engine intake. (I don't have a picture yet . . I'll get one soon.)

The other(on the 2002) was under and behind the throttle body. This one has a 90 degree angle to it that was cracked on the outside edge.

If all else fails follow the vacuum diagram under the hood and check all of the hoses.

EGR Solenoid for 1990 Geo Storm

I have a 1990 Geo Storm that needed a new EGR Solenoid.  You can't buy them anywhere new, and the used ones are ~$150.00 or more.

I found a replacement.  You can use a 1994 Chevy/GMC 25/3500 Solenoid.  Works the same.

You'll need to modify the electrical connector on both the solenoid and the harness.  Nothing serious I used a pair of small wire cutters to make the mods.  

The pins on the harness and the solenoid both line up, but because the connectors are physically different you'll need to modify the harness connector and remove a small plastic stub on the solenoid.

You'll notice that if the wiring harness connector didn't have the outside lip??? it would fit inside the solenoid connector.

1.  On the solenoid there is a plastic stub between the two pins.  Remove it.

2.  On the wiring harness connector(mine is the blue euro type connector).   Remove the outside part of the connector (the lip???)  I cut my all the way back.

3.  Connect the harness to the solenoid.

4.  Connect the EGR hoses backup to the ports.  Ignore the port with the filter on it.
