[Shotimes] EGR valve?

[Paul Nimz]

DL30 DIAGNOSTIC TROUBLE CODE (DTC) 332: VERIFY VACUUM IS PRESENT AT EGR
VALVE

DTC 332 indicates the PFE/DPFE sensor signal to the Powertrain Control
Module (PCM) did not change when the PCM output a duty cycle to the EVR
solenoid requesting EGR flow.

Possible causes:

-- Vacuum hose leaks.

-- Icing.

-- Obstructed vacuum hoses.

-- Obstructed EGR passage.

-- Damaged EVR solenoid.

-- Damaged PFE/DPFE sensor.

-- Damaged EGR valve.

-- Damaged PCM.

 Key off.

 Disconnect and inspect vacuum hose between EVR solenoid and EGR valve for
blockage, kinks, etc. Service as necessary and reconnect after inspection.

 Disconnect vacuum hose at EGR valve and connect hose to a vacuum gauge.

 Rerun Key On Engine Running (KOER) Self-Test while observing vacuum gauge.

 Is vacuum reading less than 1 in-Hg (3kPa) throughout the test (disregard
DTC output)?
