This code means in most cases the EGR exhaust gas supply passage is plugged in the intake manifold, to test this just hold the EGR open at idle it should make the engine run very rough and then die, if not the passages plugged with carbon residue and must be cleaned. This code is common on cars with over 100,000 miles.

I have a Ford F-150 xlt 4.6 with a p0401 code.


code p 0401 refers to exhaust gas recirculation (EGR) system---insufficient flow detected==== causes ---hose leak/blockage, basic setting not carried our (if applicable)---wiring---EGR valve ---EGR solenoid ---ECM
when you have done everything make sure that you use a scan tool to reset the ECM
Items that you haven't mentioned are wiring and substituting the ecm with a known operational one
bad wiring and connections / ground , broken in side the insulation may cause the problem as well

Diagnostics code po401 honda passport not shifting


code p 0401 refers to exhaust gas recirculation valve (EGR) system insufficient flow detected ====causes --hose leak/blockage --basic setting not carried out (if applicable)--wiring--EGR valve --EGR solenoid---ECM
has little to do with not shifting unless the leak is affecting the vacuum actuator for the transmission
so check for vacuum leaks in hoses in the engine bay

What does a po430 code mean on a mercury cougar


EXHAUST RELATED ERROR CODES

There are 711 possible PO generic DTC error codes. Only 7 of the 711 codes are exhaust related.

PO401: Insufficient EGR Flow

PO402: Exhaust Gas Recirculation (EGR) Excessive Flow Detected

PO410: Secondary Air Injection System Malfunction

PO420: Catalyst System Efficiency Below Threshold (Bank 1)

PO421: Warm-Up Catalyst Efficiency Below Threshold (Bank 1)

PO430: Catalyst System Efficiency Below Threshold (Bank 2)

PO431: Warm-Up Catalyst Efficiency Below Threshold (Bank 2)

THINGS TO ASK YOURSELF OR YOUR CUSTOMER

Have there been any driveability or performance issues with the vehicle, have there been any recent repairs or tune-up work performed, if so was the check engine light reset and were the codes recorded on previous repair orders.

Do not rely on scan tool data alone. In most applications, the customer will have the check engine light reset prior to repair. If the original cause of converter failure is intermittent, only the catalyst failure code may show up

Check light on,problem shows on p 0401


P0401-Insufficient flow in the exhaust gas recirculation system (EGR-valve). Check your gas cap for cracked seal, check EGR valve (make sure all vacuum hoses aren't leaking), check also VSV (vacuum switching valve) for proper operation. Its best to get an owner's manual or an experienced mechanic to diagnose!!hopefully this helpd
