I have a 2001 stratus R/T 3.0L and I have a trouble code of P0403 which is EGR control Circuit. My car runs fine at any speed but when I come to a stop or left of the gas under five miles an hour the car will stall out and kind of surge then die. It happens more so when the defroster is on, but not always. I have already replaced the EGR Valve and the battery but still have a problem. Does anyone have any information about this issue?

 

Welcome to DF
Here is a test for the EGR circuit or solenoid.
EXHAUST GAS RECIRCULATION (EGR) SYSTEM
25-20 EMISSION CONTROL SYSTEMS
NOTE: Passage of air should be checked by blowing the
valve port.
5. Reinstall the EGR valve, using a new gasket, and tighten to
the specified torque.
Tightening torque:
<2.4L ENGINE> 19 ± 3 N⋅m (14 ± 2 ft-lb)
<3.0L ENGINE> 22 ± 4 N⋅m (16 ± 3 ft-lb)
EGR PORT VACUUM CHECK 1. Disconnect the vacuum hose (green stripe) from the throttle
body EGR vacuum nipple and connect a hand vacuum
pump to the nipple.
2. Start the engine.
3. Measure engine vacuum at idle.
Standard value: 51 kPa (15 in Hg) or more
4. Reset the vacuum pump to "0" (Release vacuum).
5. Using a stop watch, measure how long it takes for the
vacuum gauge to reach 51 kPa (15 in Hg).
Standard value: 1.0 second or less
6. If it takes more than 1.0 second for the gauge to reach 51
kPa (15 in Hg), the EGR may be restricted and should be
cleaned.
EGR SOLENOID CHECK
1. Disconnect the vacuum hose from the EGR solenoid.
NOTE: When disconnecting the vacuum hose, always make
sure that it can be reconnected at its original position.
2. Disconnect the harness connector.

3. Connect a hand vacuum pump to nipple of the EGR
solenoid.
4. Check airtightness by applying a vacuum with voltage
applied directly from the battery to the EGR solenoid and
without applying voltage.
5. Measure the resistance between the terminals of the EGR
solenoid.
Standard value: 29 − 35 Ω [at 20°C (68°F)]
6. Replace the solenoid if resistance is out of specification.
