EGR Vacuum Solenoid, cavalier 1998 standard 2.2 lts.

I believe it is on the pass side of the head.(EGR) exhaust gas recirculator .it alows the engine to re burn left over fuel in the exhaust.unfortunately the pasage way gets cloged with carbon buildup causing egr failure.this is very hard to clean and should not be done by a novice DIY. some times SEAFOAM will clear it out if it is not compleatly cloged it is worth a try.

1998 Cavalier 2.2L I'm pulling codes of PO404 and PO405 The First says EGR Flow CKT Range/Perf The second is a Circuit Low Input for EGR Sensor A. PO405 is a constant code while 404 came up only once, but...

In the top picture you can see egr adapter, three bolts, the egr valve mounts to adapter. Hope the picture gives you some orientation? You can see the 5 wire connector and wire colors. The bottom picture should be the egr valve.

I just did a code scan on my 1992 Chevy Cavalier RS 6-cylinder and the codes that came back were 32 and 33. What do they mean?

DTC - 32 EGR system failure
DTC - 33 MAP sensor circuit error (signal high indicating low vacuum)

The EGR failure is causing the DTC 33 code to show up. Check the vacuum lines to the EGR valve.

Good luck and keep me posted
