SOURCE: Failed Emissions test. OBD

Rich:

The trick to setting all the monitors is:
Make sure you have more than 1/4 tank of fuel but no more than 3/4.
Clear codes then Do Not cycle key off. Start vehicle and drive,make sure you do at least 2 minutes of steady spead between 40-50 mph and at least 2 minutes at 50-65 mph, usually about a 20 to 25 mile drive will set them..
If you turn the ignition off before the monitors complete then EVAP will have to see a 6 hour cold soak before it will attempt to run again.

SOURCE: EGR Sensor/valve replacement

The EGR is a three part series; the valve, soleniod, and sensor. They are fairly easy to change, a few hours with a buddy. They are located on the top back, center of the engine. Take a look you will see something that is small and cylinder like with a wire connected to the top, that is the vavle. I would replace all three at once as they are all together and you have to take of one to take of the others. The total price will cost you about $250 in parts. However, you must know your engine type on the Sable/Tarus as the parts are different per engine.

SOURCE: P1401 still after replacing EGR pressure and EGR valve

Yes that is what is wrong the intake manifold is plugged with carbon restricting EGR flow you need to clean out the ports to correct the problem if you run the car to long you will burn the DPFE ( the EGR pressure sensor ) out agian

PO400 check engine light is on seems to run normal what to do?


P0400 - Exhaust Gas Recirculation Flow Malfunction
The exhaust gas recirculation (EGR) valve is vacuum controlled valve that regulates the amount of exhaust gases that re-enter the cylinders. The powertrain control module (PCM) determines how much based on engine load, temp, and other conditions. If the PCM detects that the amount of exhaust gases entering the cylinder were insufficient or non-existent, this code is set.

No symptoms will likely be noticed by the driver other than the MIL (malfunction indicator lamp). However, non visible symptoms will be increased combustion temperature and increased Nox emissions. A code P0400 may mean that one or more of the following has happened:
- Plugged EGR passage which restricts the flow of exhaust gasses
- Faulty EGR solenoid
- Faulty EGR solenoid wiring/harness
- Vacuum lines damaged/disconnected to the EGR valve solenoid or to the EGR valve
- Faulty EGR valve

Check it and keep us updated.

99 5.4 Expedition issues


P0401 - EGR Flow Insufficient Detected The EGR system is monitored during steady state driving conditions while the EGR is commanded on. The test fails when the signal from the DPF EGR sensor indicates that EGR flow is less than the desired minimum.
  • Vacuum supply
  • EGR valve stuck closed
  • EGR valve leaks vacuum
  • EGR flow path restricted
  • EGRVR circuit shorted to PWR
  • VREF open to DPF EGR sensor
  • DPF EGR sensor downstream hose off or plugged
  • EGRVR circuit open to PCM
  • VPWR open to EGRVR solenoid
  • DPF EGR sensor hoses both off
  • DPF EGR sensor hoses reversed
  • Damaged EGR orifice tube
  • Damaged EGRVR solenoid
  • Damaged PCM

P1299 - Cylinder Head Over Temperature Protection Active Indicates an engine overheat condition was detected by the cylinder head temperature (CHT) sensor. An FMEM Strategy called Fail-safe Cooling was activated to cool the engine.
  • Engine cooling system concerns
  • Low engine coolant level
  • Base engine concerns

P0300 - Random Misfire The random misfire DTC indicates multiple cylinders are misfiring or the PCM cannot identify which cylinder is misfiring.
  • Camshaft position sensor (CMP)
  • Low fuel: less than 1/8 tank
  • Stuck open EGR valve

P0443 - EVAP Control System Canister Purge Valve Circuit Malfunction The PCM monitors the EVAP canister purge valve circuit for an electrical failure. The test fails when the signal moves outside the minimum or maximum allowable calibrated parameters for a specified purge duty cycle by PCM command.
  • VPWR circuit open
  • EVAP canister purge valve circuit shorted to GND
  • Damaged EVAP canister purge valve
  • EVAP canister purge valve circuit open
  • EVAP canister purge valve circuit shorted to VPWR
  • Damaged PCM

P1451 - EVAP Control System Canister Vent Solenoid Circuit Malfunction Monitors the canister vent (CV) solenoid circuit for an electrical failure. The test fails when the signal moves outside the minimum or maximum allowable calibrated parameters for a specified canister vent duty cycle by PCM command.
  • VPWR circuit open
  • CV solenoid circuit shorted to PWR GND or CHASSIS GND
  • Damaged CV solenoid
  • CV solenoid circuit open
  • CV solenoid circuit shorted to VPWR
  • Damaged PCM

P1309 - Misfire Monitor Disabled When the misfire monitor is disabled, usually due to the input signal generated by the camshaft position (CMP) sensor, by sensing the passage of teeth from the CMP wheel.
  • Camshaft position sensor
  • Powertrain control module
  • ECT, MAF, and CKP sensors

with the codes you have here I would look in the direction of the egr valve first because that will cause the bucking and stalling, and the misfires, but so will the canister vent solonoid. the misfire codes and the cylinder overtemp code could be from overheating or because if the misfires.

99 dodge stratus dies while driving


Were the plugs covered in oil? With the plugs that go through the valve cover you might need new seals. Did you replace the plug wires? You need to scan it for codes. It's most likely a missfire, but it could be a bad speed sensor (also called, VSS vehicle speed sensor, cam position sensor,or crank position sensor).

1995 mercury villager check engine code p1200 injector open


P0400 = EGR Flow
P0325 = knock sensor (Do not ever change a knock sensor, they don't affect anything and cost $600 to replace for absolutely no gain)
P1200 = I can't find this one. I think it's injector flow
report back on what you find.
Egr flow may be plugged egr passages or a bad solenoid.

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.

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.
