Fault Code 32
Description: Logic module did not see a change in air/fuel
ratio when EGR circuit was activated
Power loss light: Off
Limp-in mode: None
EGR valve stuck open or closed - If the vehicle fails emmisions,
then the valve may be shut. If the enigne runs poorly at low rpm
or at idle, the valve may be stuck open. It may be the valve or the
transducer valve. Test the transducer valve vacuum output. At idle,
the transducer valve vacuum should be mostly bled, and there should be
very little, if any vacuum at the output. When the engine is revved,
the vacuum should increase. If the transducer is functioning properly,
replace the EGR valve.
Bad EGR solenoid or Canister
purge/EGR solenoid - The solenoid is located in the right, front
fender next to one to three other solenoids. See the Understanding
Solenoids page for information about how to test and repair solenoids.
Bad connection or wiring - Check the wiring and connections between
the solenoid and the logic module (or SMEC). Clean and regrease any
corroded connectors with dielectric grease and repair any shorts.
- The EGR solenoid was deactivated, but the oxygen sensor reading did not
