Here is the code description for code p1404 I forgot to post it on my first post sorry about that. What you need to do is take it back to the dealer that charged you to fix it. You need to make them fix it at no additional charge.
The exhaust gas re-circulation (EGR) valve position sensor is monitored by the power-train control module (PCM). The five volt reference circuit, low reference circuit and the EGR valve position signal circuit are used by the PCM to determine the EGR valve position. When the ignition switch is turned "on", the PCM records the EGR learned minimum position. The PCM compares the EGR learned minimum position parameter to the EGR position sensor parameter. If the PCM detects that the EGR valve is still open when the PCM is commanding the EGR valve closed, DTC P1404 sets.
Conditions for running the DTC:
* The engine is running.
* The Ignition one signal voltage parameter is between 11-18 volts.
* The EGR valve is commanded to zero percent for twenty seconds after the EGR valve has been commanded to open more than forty percent for 0.5 seconds.
Conditions for setting the DTC:
* The EGR position sensor parameter is 0.2 volt more than the EGR learned Minimum position parameter when the desired EGR position parameter is commanded to zero percent for twenty seconds.
* The EGR position sensor parameter is more than forty percent and is steady for 0.5 seconds after a test failure and before the next test will be run.
* The above conditions are met four times.
Action taken when the DTC sets:
* The control module illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.
* The control module records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the control module stores this information in the failure records. If the diagnostic reports a failure on the second consecutive ignition cycle, the control module records the operating conditions at the time of the failure. The control module writes the operating conditions to the freeze frame and updates the failure records.
Conditions for clearing the mil/DTC:
* The control module turns "off" the malfunction indicator lamp (MIL) after three consecutive ignition cycles that the diagnostic runs and does not fail.
* A current DTC, last test failed, clears when the diagnostic runs and passes.
* A history DTC clears after forty consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
* Clear the MIL and the DTC with a scan tool.
* Inspect for excessive deposits on the EGR valve pintle or seat. Remove the EGR valve and check for deposits that may interfere with the EGR valve pintle extending completely or cause the pintle to stick.
* If the problem is intermittent, refer to intermittent conditions.
