SOURCE: P0401. P0133, P1131- emmision test

Based on what the tech manuals say I would change the DPFE sensor for the EGR Valve, careful not to tear the special silicone rubber hoses that go to it from the exhaust, as a Ford dealer tech I saw these codes allot, and the DPFE sensor was almost always the issue or the hoses going to it.

SOURCE: 99 dodge caravan parking lights stay on after engine is off.

I had the same problem on my Chrysler Sebring but it was with the headlights staying on. The lights are on a relay called a "delay relay" of which will allow the lights to stay on for a minute after shutting off the ignition (after using your lights let's say when its dark). This of course helps provide light for you to see to walk to your house, keys, etc. But sometimes these relays stick on and just need to be replaced.

SOURCE: Engine light on in 2000

it is your EGR Valve. EGR stands for Exhaust Gas Recirculation. It is part of the vehicle emmissions system, and is used to reduce combustion temperature and pressure to control Oxides of Nitrogen. There are generally three parts to the EGR system: the EGR valve
, an actuator solenoid, and a differential pressure sensor EGR (DPFE). These things work together to deliver the correct amount of recirculation based on engine temperature, load, etc. The P0401 code means that OBD detected an insufficient amount of EGR.

Causes A code P0401 most likely means one or more of the following has happened:

  • The DPFE (differential pressure feedback EGR) sensor is faulty and needs to be replaced
  • There is a blockage in the EGR (tube), most likely carbon buildup
  • The EGR valve is faulty
  • The EGR valve may not be opening due to a lack of vaccuum
Possible Solutions In fixing this code, it is quite common for people to just replace the EGR valve only to have the OBD code return. The EGR valve is not always the culprit.
  • Use a vacuum pump and pull the EGR valve open while monitoring engine RPM's & DPFE voltage. There should be a noticable difference in RPM's with the EGR open
  • Clean out the EGR valve and/or tubing to remove deposits
  • Check the voltage at the DPFE, compare to specified values (refer to a repair manual for your specific model)
  • Replace the DPFE sensor (with a good quality / OEM one)
  • Replace the EGR valve
LOCATION:
drivers side of the engine bay, just under the intake manifold plenum where the throttle body bolts up! If you take the air snokel off you'll see it better! It has a remote mountted vaccum solenoid with a 2 wire connector going to it that you should be able to see near the throttle body.
Follow the hose from the solenoid down to the valve and you'll find it!

P0442 refers to a small leak in the Evaporative Emissions System(It purges fuel tank vapors into the engine to be burned rather than vented into the atmosphere). From time to time the PCM pressurizes this system to check its integrity. If it senses a small leak, then it sets this code. 

Is your gas cap on tight? Recheck it.

The evaporative emission system is probed by applying vacuum to the EVAP system and monitoring for a vacuum decay.
 The engine control module (ECM) monitors the vacuum level through the fuel tank pressure sensor signal.

The EVAP canister purge valve and the EVAP vent solenoid are turned on at the nick of time, allowing the engine to **** up a small vacuum on the entire EVAP system.

 After the requisite vacuum level has been obtained, the EVAP canister purge valve is switched OFF, locking the system entirely.

 If sufficient vacuum level cannot be derived, a large leak is indicated. This can be caused by the following conditions 


The P1684 code simply means that the battery has been disconneted within the last 50 starts.

I just replaced the egr valve in my 1997 dodge caravan 2 days ago. The service engine light came back on, and I got the same p0401 code. What should I look for now?


it may help to tell what engine you have. P0401 doesnt mean the egr valve was bad, it means the egr isnt opening for some reason OR not flowing. Egr valves rarely are "bad" check if all vacuum lines are connected and clear. the egr vacuum solenoid is famous for being bad. als make sure the passage from the egr valve to the intake manifold is clean and flowing. Its like flushing a toilet thats clogged.. All the valves are working, but its not flowing.

Ihave dodge caravan sport 2001 and ihave this code in my car-p0442 how i fixed ?


This indicates a fuel vapor leak in the EVAP control system. It means a very small leak has been detected. .The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.

A code P0442 most likely means one or more of the following has happened:
  • A loose or improperly affixed gas cap
  • A non-conforming gas cap (i.e. not factory/original brand)
  • A small leak/hole in a fuel vapor hose/tube
  • Other small leak in EVAP system
  • Faulty vent o-ring seal

With a P0442, the most common repair is to:
  • Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
  • Otherwise, replace the gas cap, or
  • Inspect the EVAP system for cuts/holes in tubes/hoses
Few places to check - rubber hose under air box (requires removing the air box) and hoses connecting to EVAP system under the van on the drivers side.

Code, p0442 p0445


P0442 - Evaporative Emission Control System Leak Detected (small leak)

This indicates a fuel vapor leak in the EVAP control system. It means a very small leak has been detected. In fact, the leak can be from a hole as small as 0.04" in diameter. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.

Symptoms: You likely won't notice any drivability problems.

Causes: A code P0442 most likely means one or more of the following has happened:
* A loose or improperly affixed gas cap
* A non-conforming gas cap (i.e. not factory/original brand)
* A small leak/hole in a fuel vapor hose/tube
* Other small leak in EVAP system
* Faulty vent o-ring seal

Possible Solutions: with a P0442, the most common repair is to:
* Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
* Otherwise, replace the gas cap, or
* Inspect the EVAP system for cuts/holes in tubes/hoses



P0445 - Evaporative Emission Control System Purge Control Valve Circuit Shorted.
Possible Solutions: with a P0445, the most common repair is to:
* Bad or loss contact wires
* Check harnesses, replace it


Hope helps (remember to rate this).

2001 Sable gets P0401 first, then gets P0442 some miles later. When P0442 sets, so does engine check light. Car runs well. What could cause this sequence of error codes?


This could be a small evaporative system leak. Check the gas cap to be installed fully. If fully installed may need replaced.
