SOURCE: low pressure exhaust sensor faulty on passat 57

If you have low pressure in the exhaust manifold, then there would an exhuast leak somewhere from the exhaust manifold to the tail pipe. These leaks tend to get bigger over driving time. It may be the exhaust manifold gasket, or a crack in the manifold. Give a good listen for a sputtering sound. Part of the exhaust pipes have to be removed for access to the manifold. A good spray of PB breaker will help a lot with the bolts here.
Escaping gas is bad for the environment. This also causes gas to enter the manifold and make its way to the valves. The temperature of the incoming air is very cold compared to the combustion chamber and can cause damage the your valves by stressing them.
If you find no leak, then you may consider the sensor may be faulty or the leak is very small.
Good Luck.

SOURCE: p0471 and p2002 codes, Audi A6 2.0 DPF S-Line Auto

A6 2.0 TDI 1997
Got same problem around 35000Km. Engine light on with same error P0471. I was in France, Audi reset error and found nothing suspect. 4 weeks later same problem. (I felt engine was executing filter regeneration cycle very often). After 1 more week, Exhaust symbol came into large display and engine into safe mode (max 90Km/h). Contacted my Audi dealer in Belgium. They immediately told me pressure sensor (measures obstruction over DPF) was defective ; happens more often. Car was just beyond 2 Y old. Replaced under warranty. No more problems.

2003 ford expedition check engine light is on. It is reading a p405 code which is the egr sensor. I have change the sensor and the pig or electrical code twice . I brought the sensor from ford.

This DTC says nothing about changing the sensor or the connector or pig tail ! It's a circuit voltage low code
P0405 - DPF EGR Sensor Circuit Low Voltage Detected See DTC P1400 Problem with wiring or PCM !
P1400 - DPF EGR Sensor Circuit Low Voltage Detected The EGR monitor checks the DPF EGR sensor signal to the PCM for low voltage. The test fails when the average voltage to the PCM drops to a voltage less than the minimum calibrated value.
  • DPFEGR circuit short to GND
  • Damaged DPF EGR sensor
  • VREF short to GND
  • Damaged PCM
A DPF EGR PID reading less than 0.2 volt with the key ON and engine OFF or running, indicates a hard fault.

Hi i have honda accord 2009 diesel have dpf problem. Now replaced by honda but dpf check system light comes after few hundred miles. Nothing comes in their dignoistic machine plus out side temperature...

I don't know much about the diesel particulate filter system yet other than what I have read.

All the articles on the subject I have seen so far indicate the trigger for starting the automatic DPF cleaning cycle is excessive exhaust back-pressure. When the pressure sensor in the exhaust detects excessive pressure the engine management values are changed to make the exhaust very hot and a special solvent from an on-board reservoir is forced into the system and the cleaning process of the DPF is underway.

The articles suggest topping up the reservoir of special solvent is a routine service item. Anecdotal evidence suggest neither the cleaning process or the topping up are automatic or routine but rather another way for dealers to rip-off customers.

When the cleaning process no longer restores minimal back-pressure the DPF must then be replaced at what anecdotal evidence is a very high cost.
I could be wrong but I suspect before the engine management system recognises excessive back-pressure to be a problem and record it as a fault it would have to record a certain number of instances in a certain time-frame and if that criteria isn't being met there will be no faults stored.
Certainly this is a case for an obd recorder to be fitted to your car to record the live data which can be analysed by the dealer later.

I speculate the pressure sensor, wiring or connectors might be faulty or inaccurate or you really do have a back-pressure problem, either because the DPF they fitted is faulty or of poor quality, the work is of poor quality or because there is something wrong with the rest of the exhaust system.

Personally, because I have experienced back-pressure problems increasing during a journey being caused by exhaust silencer boxes I would start by removing everything rear of the DPF and give each part a shake and compare the weight with a new one of the same type.
Just my opinion you understand.

I would need to refer to a wiring diagram and an overview of the engine management system to form an opinion whether the exterior temperature indicator is a coincidence or is linked.

Good luck!

Auxilary emissions controls

OBD2 fault codes have no cut and dry fix for every car that has it in memory. Here is the general info on the code. This code refers to the EGR valve back pressure sensor called the "DPFE" sensor
P1401 - DPFE Circuit High Input
Symptoms - Engine Light ON (or Service Engine Soon Warning Light) 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.

    I have a scan tool that says my egr valve system not ready on my Ford f150 5.4 and my catylist reads not ready how can I fix this problem

    ABout EGR codes, there are alot choive to look or diagnostic... are you chec or replace the vacuum lines as well? If there is a leak, the DPFE will read incorrectly.

    Did you reset the PCM or disconnect the battery after the repair? Assuming all fuses are good, the P1401 indicates a possible wiring fault. Check the connector. Is it clean? Is it pushed in all the way? Are the wires in good condition?

    Since the DPFE has been replaced, likely there is a restriction in the EGR line some where. This could also be a bad EGR valve. But first ensure that the EGR valve vacuum line is attached and leak free.

    If no problem found, then the EGR passageways in the throttle body should be cleaned. Carbon will build up and block the EGR flow.

    If still no problem found, consider replacing the EGR valve.

    Keep in mind this information from Ford Service CD...

    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

    P1401 - DPF EGR Sensor Circuit High Voltage Detected
    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.
    DPF EGR circuit open
    VREF short to PWR
    Damaged DPF EGR sensor
    DPFEGR circuit short to PWR
    SIG RTN circuit open
    Damaged PCM

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

    Hope this helps (remember to rate and send us your comments about this answer).

    Exhaust pressure sensor a possibility if it has a DPF (diesel particulate filter). Has it had its fuel pump recall, the oil pressure light could be just the constant cranking and running the battery low.

    How do i fix a p 1401 code, what parts i need to change?


    This error is due to bad DPFE (delta pressure feedback) sensor. This sensor is located on the passenger side of the engine compartment.

    Once replaced, would fix the issue.

    Hope i helped you.
