I'm Neal and I am here to assist you. Only accept when you are happy with my assistance. If I can't help I will open your Question to other experts.
So the only code is the egr code now?
What is the exact code?
This question will remain open and I will continue to work with you even after you accept. The question will remain active for 7 days after our last communication.
Yes, the only code I get is code P1404
It sounds like your problem is going ot be in the wiring or a bad connection at the pcm. Here is the info and diagnostic procedure if you want to try and track the issue down yourself.
CIRCUIT DESCRIPTION The Powertrain Control Module (PCM) monitors the Exhaust Gas Recirculation (EGR) valve pintle position input to ensure that the valve responds properly to commands from the PCM. When the ignition switch is turned ON, the PCM learns the EGR learned minimum position. The PCM compares the EGR learned minimum position to the EGR position sensor when the EGR valve is commanded closed. If the EGR position sensor indicates that the EGR valve is still open when the PCM is commanding the EGR valve closed, this DTC will set.CONDITIONS FOR RUNNING THE DTC The system voltage greater than 10 volts. The EGR valve is enabled.CONDITIONS FOR SETTING THE DTC ^ The EGR position sensor is 0.2 volts more than the EGR learned minimum position when the Desired EGR Position is commanded to 0 percent. ^ The above condition is present for 80 seconds.ACTION TAKEN WHEN THE DTC SETS ^ The control module illuminates the Malfunction Indicator Lamp (MIL) when the diagnostic runs and fails. ^ The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Freeze Frame/Failure Records.CONDITIONS FOR CLEARING THE MIL/DTC ^ The control module turns OFF the Malfunction Indicator Lamp (MIL) after 3 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 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic. ^ Use a scan tool in order to clear the MIL and the DTC.DIAGNOSTIC AIDS Inspect for the following condition: 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. See: Computers and Control Systems > Initial Inspection and Diagnostic Overview > Intermittent ConditionsTEST DESCRIPTION
The numbers below refer to the step numbers on the diagnostic table: 2. This step verifies that the malfunction is present. 4. If DTC P1404 will only set under certain conditions, the malfunction may be intermittent. Refer to Diagnostic Aids. If an intermittent wiring problem is not present, test for a faulty connection at the PCM or the EGR valve. If the connections are OK and DTC P1404 continues to set, replace the EGR valve.
