What do code 1401 mean for my 2001 Ford crown Victoria police intercepted ?


2001 crown vic, code # po1401. this code has to do with the egr system, the first thing is to check the dpf sensor, this sensor tells computer that the egr valve is working, there are two hoses the run off sensor and go into exhaust lines, check the hoses ,make sure they are on and not split, if hoses are good then start by replacing that sensor. here is a pic of it.and also the hoses86ba1833-6384-4844-833d-84eadda90752.jpg1944c06a-cc52-4fd8-9c4f-ae244e7ad0df.jpg

The PCM is programed for the LS engine parameters and now that you have changed engines the signal from the new engine are out of parameters> Either see if you can get the PCM reprogrammed at a dealership or purchase a new PCM and program the chip with the police engine interceptor to the vehicle> you may also return to the place where you got the engine and purchase the PCM for the police vehicle.

Need to find out what the emissions read P1401


P1401 - DPFE Circuit High Input

Description Of The Code:
The EGR monitor checks the DPF EGR sensor signal to the PCM for high voltage. The test fails when the average voltage to the PCM goes to a voltage greater than the maximum calibrated value.

Possible Causes:
  • DPF EGR circuit open.
  • VREF short to PWR.
  • Damaged DPF EGR sensor.
  • DPFEGR circuit short to PWR.
  • SIG RTN circuit open.
  • Damaged PCM.

  • Possible Solution:
    A DPF EGR PID reading greater than 4.5 volts with the key ON and engine OFF or running indicates a hard fault.

    P0401 - EGR Flow Insufficient Detected The EGR system is monitored during steady state driving conditions while the EGR is commanded on. The test fails when the signal from the DPF EGR sensor indicates that EGR flow is less than the desired minimum.
    • Vacuum supply
    • EGR valve stuck closed
    • EGR valve leaks vacuum
    • EGR flow path restricted
    • EGRVR circuit shorted to PWR
    • VREF open to D.P.F. EGR sensor
    • D.P.F. EGR sensor downstream hose off or plugged
    • EGRVR circuit open to PCM
    • VPWR open to EGRVR solenoid
    • D.P.F. EGR sensor hoses both off
    • D.P.F. EGR sensor hoses reversed
    • Damaged EGR orifice tube
    • Damaged EGRVR solenoid
    • Damaged PCM
    Perform KOER self-test and look for DTC P1408 as an indication of a hard fault. If P1408 is not present, look for contamination, restrictions, leaks, and intermittents.
    not likely the PCM, engine computer. they seldom go bad.
    report back findings.

    Speedometer and odometer does not work in 1998 Crown Vic police interceptor


    Either the speed sensor,or the dash cluster is of fault. Have Auto Zone test the speed sensor,if ok ,,, I would replace the cluster ( buy used ) much cheaper.
    Please rate this.

    Ford Crown Vic p0300 random cylinder misfire


    take a look at the EGR valve it could be either vacum controlled or electronic either way what seems to be the problem is that the valve is stuck in the open position until the engine warms up you can gently tap the egr valve with a small hammer or a screw driver and you can see that it runs smooth, now if the egr valve is vacum controlled replace the valve. if it is electronoc controlled replace the valve and the module for the egr valve.
