During a DMV inspection my vehicle failed because of these codes: P0401,P0700,P1739. What should I do? and what is the estimated cost?


P0401=EGR valve insufficient flow
P0700=transmission control system malfunction
P1739=transmission control module controller circuit

Get the EGR valve checked. It may be that a vacuum line is off. But worst case, say you need a new EGR valve. You can price one at autozone.com. Then find out what a shop would charge for labor to put it in. The transmission codes may be intermittant faults. If your car seems to be running fine, reset the codes and they may not come back until after your test, if ever. If the codes come right back, you'll have to take it to a transmission shop for check out. Any major auto parts store has a code reader that can reset your codes for free.

Just to be clear, have all your work done and then reset your codes. Then you will have to drive your car normally for a few days before taking your DMV inspection. There is a test they will run to see if enough drive cycles (a start, run, and shut down=one cycle) have been accomplished after a code reset. This prevents people from resetting the codes and immediately taking the test without any work being done.

Check engine light stays on the code that keeps coming up is P0401 changed egr valve clened out carbon build up also smell gas when first start not driving and fuel millage not as good car runs good though...


Could be a EGR vacuum issue or temp sensor issue

Common Problems That Trigger the P0401 Code
  • Restriction in the EGR passages, usually caused by carbon buildup
  • Lack of a proper vacuum signal to the EGR Valve from EGR Vacuum Solenoid
  • EGR Vacuum Modulator is defective
  • EGR Temperature Sensor is defective
  • EGR Valve is defective

1998 ford escort code P0401 I need to know what this code is for. Thank You.


This code is an EGR code for insufficient amount of egr. It could be that the egr tube is clogged or the egr itself is bad or there is not enough vacuum to open the egr properly. There is also a sensor called the DPFE(differential pressure feedback egr) is faulty.

Code on diagnostics p0401


Code on diagnostics p0401:

What is going on?
Exhaust Gas recirculation low flow detected means that: there is vacuum problem in the EGR system - between the combustion chamber, EGR valve (mechanical - blown up diaphragm or clogged airlets/hoses) , EGR Modulator Valve (mechanical - blown up diaphragm, dirty EG/air filter or clogged airlets/hoses) and Vacuum Switching Valve ((mechanical - blown up diaphragm or clogged airlets/hoses OR electrical - VSV not properly synchronizing with the ECM, for instance).

Effects?
This causes the combustion chamber temperature to increase and produce Oxides of Nitrate (NOx) that is out of an acceptable emission range. This triggers the Malfunction Light (check engine light) to stay on (after a couple of driving cycles)!
Solution: Focus on EGR airways (hoses...) and organs (EGR valve, EGR Modulator, VSV), clean, check or replace the defected one. VSV seems to be criticale as it plays electrical & mechanical function. Once the repair is done, Clear the P0401 code using an OBII scanner.
