SOURCE: Code P0404 Exhaust Gas Recirculation Control Circuit. How Do I g?

it is probably not the egr it self it is the control module plugged in to it. unless it is one which the module is built in to the egr valve. check with your auto parts supply and see if the module and egr valve can be ordered separate. I believe they are separate on a chrysler product. Mike

SOURCE: engine keeps missing. unknown codes

Code 1682 indicates low battery voltage. This could be a problematic alternator, which would likely cause misfiring. Autozone should be able to check this for you for free.

Code 1391 indicates the computer can not see the crank or cam sensor signal. This would likely be a result of the misfires.

Code 0320 indicates the crankshaft position sensor reference signal could not be found while the engine is cranking.

All of these issues point to either a cam/crank sensor malfunction or a charging system problem, either or both of which could cause the misfiring.

Wiring diagrm for egr valve 2009 jeep wrangler 3.8


JK jeep, i have 08 and full docs.
it wires to the PCM, same wire colors
as you can see drawing dont work right in fixya.
they get "crunched" badly"
the EGR is PWM modulated,
first is to clean in. the exhaust path must be good
the EGR must not stick closed or open.
p0405 means the pin on sensor part is stuck low.
tell me in most cases, the valve is stuck closed.
clean it is best first action.

the monitor pin is at X, this tells the PCM where the EGR moved
per PCM command. (called feedback) yours is hard stuck.

2001 jeep wrangler sport 4.0 liter engine starts then shuts off. Is this the crankshaft sensor


engine stalls
there are over 50 reasons for stalls. (even burned intake valve or even a 10cent valve keeper ,missing)
but in physics (we use gauges to find truth)
it 5 reasons, what to TEST or Gue$$>
the list and matching tools if you ask.
  • battery power never dropping below 13.3v running. or PCM can shut down near or below 11v.
  • Lost engine compression. 1 or more cylinders.
  • lost spark or timed wrong. (cams can go off time and take spark with it)
  • bad fueling. to much and too little.
  • EGR stuck open. if you have one, many 4l dont, it uses a detuned cam to , prevent NOX commissions.
want to test?

Backfiring after running a cuppel minuts then runs fine only does this when first start it up


There is a thing called a EGR valve(exhaust Gas Recirculation).It allows different amounts of exhaust gases back into the engine.Its vacuum operated but is also hooked up to the ECU.In short.Get it checked because your symtoms sound like it could be it.Check all its hoses for leaks etc.The unit itself is near the inlet manifold.You can push it in to check it's not stuck but you still have to check for tube leaks.Hope this helps

What does code p042e mean


P-042e-Exhaust Gas Recirculation Control Stuck Open
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
P042E-EXHAUST GAS RECIRCULATION CONTROL STUCK OPEN

During regeneration of the aftertreatment Diesel Particulate Filter the Exhaust Gas Recirculation (EGR) valve is commanded to be in the closed position. If the EGR valve is not closed then a temperature rise will occur at the EGR valve orifice. The Engine Control Module (ECM) monitors the orifice temperature of the EGR valve and will set the fault if the temperature is above a calibrated threshold.

Unless the wiring has been tampered with going to the egr valve, replacement of the egr valve is the most likely scenario that will repair this for you.

No Heat 2001 Wrangler


you have a faulty thermostat in your jeep. the thermostat is on the engine where the top cooling hose attaches to the motor. it will look like a small valve type thing with a spring that holds the brass part against the steel. if you are replacing this yourself than you will want a 195 thermostat.

The EGR valve helps your car more efficiently and completely burn fuel by recirculating a portion of your exhaust and running it through the combustion process again. When the EGR valve goes bad, it must be replaced.

The EGR valve, or Exhaust Gas Recirculation valve, is a vacuum controlled valve which allows a specific amount of your exhaust back into the intake manifold. This exhaust mixes with the intake air and actually cools the combustion process. Cooler is always better inside your engine. The exhaust your EGR valve recirculates also prevents the formation of Nitrogen related gases. These are referred to as NOX emissions, and are a common cause for failing emissions testing. Unfortunately, your EGR valve can get stuck, causing NOX gases to build up. You'll know if your EGR valve is stuck or malfunctioning because your car will experience symptoms like rough idle and bucking on acceleration.

Here is a picture of where the EGR Valve is located (Accord 1999). Replacing it is fairly simple and straightforward. A vacuum line and a couple of bolts. You'll see what you have to do when you look at it.

If you are replacing the EGR Valve due to the Check Engine Light (MIL) being on with a DTC P0401 then I suggest contacting your Honda Dealer. There was a Product Update Campaign (PUD) in the fall of 1999 that corrected the problem.

Another times, the clean is the solution...I hope help yoiu with this. Good luck, and remember rated this help.

FAILED EGR VALVE


The EGR valve helps your car more efficiently and completely burn fuel by recirculating a portion of your exhaust and running it through the combustion process again. This results in a cooler, more complete burn of the fuel which decreases you car's noxious emissions by prohibiting the formation of some harmful gases.

The EGR valve is vital to your car's emission controls.

When the EGR valve goes bad, it must be replaced - it cannot be repaired.

  • EGR Valve = Exhaust Gas Recirculation Valve.
  • The EGR valve controls formation of noxious emissions.
  • Rough idle and poor acceleration can be caused by a faulty EGR valve.

  • The EGR valve, or Exhaust Gas Recirculation valve, is a vacuum controlled valve which allows a specific amount of your exhaust back into the intake manifold. This exhaust mixes with the intake air and actually cools the combustion process. Cooler is always better inside your engine. The exhaust your EGR valve recirculates also prevents the formation of Nitrogen related gases. These are referred to as NOX emissions, and are a common cause for failing emissions testing. Unfortunately, your EGR valve can get stuck, causing NOX gases to build up. You'll know if your EGR valve is stuck or malfunctioning because your car will experience symptoms like rough idle and bucking on accelertaion.

    The only short term problem is a decrease in gas mileage - but it should really be replaced before sensors become sooted or your cat. convertor gets overworked prematurely.

    --------------
    1996 PCED OBDII-Villager SECTION 1B: Description and Operation
    Exhaust Gas Recirculation System
    Exhaust Gas Recirculation (EGR) System Operation The exhaust gas recirculation (EGR) system (Figure 1 below) recirculates a portion of the exhaust gases into the intake manifold under average vehicle driving conditions to reduce combustion temperatures and exhaust gas NOx content. The amount of exhaust gas recirculated varies according to operating conditions and will be cut completely under:
    • Engine starting condition
    • Low engine coolant temperature condition
    • Excessively high engine coolant temperature condition
    • Engine idling condition
    • High engine speed condition
    • Mass air flow sensor failure
    The exhaust gas recirculation (EGR) system on the Villager uses the exhaust gas recirculation/evaporative emission (EGR/EVAP) control solenoid valve to provide vacuum to both the EGR valve and the EVAP canister when commanded by the PCM. If the exhaust backpressure is sufficient to close the EGR backpressure transducer valve, vacuum is sent to the EGR valve and allows EGR gas to flow into the intake manifold. If the exhaust backpressure is not sufficient, the EGR backpressure transducer will remain open and allow vacuum from the EGR/EVAP control solenoid to vent to the atmosphere.
    The EGR system monitor, for OBD II regulations, uses an EGR temperature sensor to monitor the EGR system. The EGR temperature sensor is a thermister located in the EGR passageway. When hot exhaust gas is recirculated into the engine, the temperature at the EGR passageway increases. This increase is sensed by the EGR temperature sensor and a signal is sent to the PCM to indicate EGR flow. If the EGR temperature sensor does not detect EGR flow when commanded by the PCM after two consecutive drive cycles, the malfunction indicator lamp (MIL) will be illuminated and a diagnostic trouble code (DTC) will be stored. The MIL will be turned off after three consecutive drive cycles are completed with no malfunctions detected. The DTC will remain stored in the PCM memory until 80 drive cycles have been completed without the same malfunction detected in the system.
    Figure 1: Exhaust Gas Recirculation (EGR) System Diagram Item Number Description 1 — EGR/EVAP Control Solenoid 2 — Air Cleaner Housing 3 — Throttle Valve 4 — EGR Temperature Sensor 5 — EGR Valve 6 — EGR Backpressure Transducer 7 — EVAP Canister
    Exhaust Gas Recirculation (EGR) Backpressure Transducer Valve The exhaust gas recirculation (EGR) backpressure transducer valve is used to control EGR. The EGR valve is operated by ported vacuum, but the ported vacuum will normally be vented off at the EGR backpressure transducer valve. As rpm increases, exhaust pressure increases and pushes on the diaphragm in the EGR backpressure transducer valve and closes the vacuum vent.
    Figure 2: EGR Backpressure Transducer Value
    Item Number Description 1 — Throttle Valve 2 — Vacuum Port 3 9D475 EGR Valve 4 9F452 EGR Backpressure Transducer Valve 5 — EVAP Canister 6 — EGR/EVAP Control Solenoid 7 — Vent
    EGR/EVAP Control Solenoid The exhaust gas recirculation/evaporative emission (EGR/EVAP) control solenoid (Figure 3) is controlled by the powertrain control module (PCM). The EGR/EVAP control solenoid controls vacuum to both the exhaust gas recirculation (EGR) valve and to the evaporative (EVAP) emission canister. When the EGR/EVAP control solenoid is off (12 V signal from the PCM) vacuum is supplied to both the EGR valve and to the EVAP canister. When the EGR/EVAP control solenoid is on (ground supplied by PCM) vacuum is vented to the atmosphere keeping the EGR valve closed and no vacuum to the EVAP canister. The PCM will command the EGR/EVAP control solenoid on at:
    • Engine starting condition
    • Low engine coolant temperature condition
    • Excessively high engine coolant temperature condition
    • Engine idling condition
    • High engine speed condition
    • Mass air flow sensor failure
    Figure 3: Exhaust Gas Recirculation/Evaporative Emission (EGR/EVAP) Control Solenoid
    Exhaust Gas Recirculation (EGR) Temperature Sensor
    The exhaust gas recirculation (EGR) temperature sensor (Figure 4) is a thermister type sensor that monitors the temperature of the exhaust in the EGR passageway. As the EGR flow increases, the temperature increases. This process creates a change in the resistance of the sensor, which decreases as the temperature increases. The signal is sent to the powertrain control module (PCM) to indicate that the EGR system is working properly. If the EGR temperature sensor does not change resistance as the PCM expects on two consecutive drives, the malfunction indicator lamp (MIL) will be illuminated and a diagnostic trouble code (DTC) will be stored.
    Figure 4: EGR Temperature Sensor Exhaust Gas Recirculation (EGR) Valve
    The exhaust gas recirculation (EGR) valve (Figure 5) recirculates portions of the exhaust gas back into the intake manifold to reduce the amount of the NOx released during combustion and to reduce combustion temperature. The amount of exhaust gases that are released into the engine is proportional to the load on the engine.
