Many things will set this code.causeing low voltage to dpfe sensor,its alot of times bad,first test egr valve with applied vacum to determine its not bad.tube running to exhaust can and does clog with carbon over years.if its clogged must be cleaned.check dpfe sensor voltage rise and fall differences correct,before just chaung things.egv pressure regulator check also.check thouroughly all wiring,it can aand does get hot ,soften an stick together shorting ang ground as it should not,, make sure pvc valve working and not leaking vacum,all hoses and fittings should be checked for vacum leaak..even a faulty maf sensor that might not set aa code will brigabout this code 1400.thouroughly tesst all components even 02 sensors should be suspect.all this fails at about the same time.take your time ,overlook nothing fix everything right the first time.dont waste your money.most of these parts are available way less than dealership and even autozone on ebay

SOURCE: 2001 ford taurus with check engine light on. code

Make sure you replaced the right one there are two sensor's for the coolant, one takes coolant temp and the other one runs the fans for the radiator. Both are located on drivers side of the block. 2 wire leads on each how ever both are different in sending readings to the computer.Both look just alike also. Just make sure you replaced the right one. Or replace both.

I have a 2006 Saab 97x 4.2i, check engine light is on the the codes that came up are p0014, and p1400. Can anyone tell me the problems


Please follow the link for info you requested on P0014
http://www.autocodes.com/p0014_saab.html

P1400 Saab
When you check engine light came on code P1400 the reason should be Engine Light ON (or Service Engine Soon Warning Light). However Saab manufacturer may have a different definition for the P1400 OBD-II Diagnostic Powertrain (P) Trouble Code. So you should chech it on our car models.
Saab P1400 Possible Solution : The crankshaft sensor signals the fuel injection computer or the ignition control when the cylinders are firing. This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time.If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver.

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.

Either code 4000 or 1400 on 2002 ford ranger 4.0 ltr v6. the right code should equate to the egr valve. I have replaced the egr valve but check engine light comes on again after reset showing same code.


code p1400 is a DPF EGR sensor CIRCUIT LOW VOLTAGE detected. most likely is a problem with the wiring to the egr or dpfe sensor. the pinpoint tests for code p1400 instruct you to test all wiring before replaceing the egr or dpfe sensor

Code p1400 on my nissan altima check engine light


P1400 - EGRC Solenoid Valve

The P1400 code is for the EGR solenoid and not for the valve. The solenoid control the opening and closing of the valve. You should check the solenoid hoses and the connector. Also check if there is voltage at the green/yellow wire.

Hope helps.

P1400 - DPFE (Differential Pressure Feedback Electronic) Sensor circuit Low Voltage

The DPFE sensor is usually not hard to change. There are 2 small rubber hoses that run from the EGR tube to it...

Replace DPFE sensor, reset engine fault codes. The Ford one is a good one and rockauto.com carries Airtex. Sometimes I hear that this change always need replace EGR valve to delet all codes. Test it.

Good luck.

Wat does code p1400 means


In order to give you accurate information. I need size of engine example 2.0 L 3.0L. but code P1400 means Differential Pressure feedback EGR circuit low input. Maybe your differential oil is low.

Engine light on 2002 Explorer. engine code P1400


This may have to do with a bad wiring. Check all the wiring associated with EGR operation. Whenever a computer throws a code about high or low circuit voltage, it is usually attributed to abnormal wiring.
