Exhaust Gas Recirculation (EGR) System Monitor—Differential Pressure Feedback EGR The Differential Pressure Feedback EGR System Monitor is an on-board strategy designed to test the integrity and flow characteristics of the EGR system. The monitor is activated during EGR system operation and after certain base engine conditions are satisfied. Input from the ECT, CHT, IAT, TP and CKP sensors is required to activate the EGR System Monitor. Once activated, the EGR System Monitor will perform each of the tests described below during the engine modes and conditions indicated. Some of the EGR System Monitor tests are also performed during on demand self-test.

  1. The differential pressure feedback EGR sensor and circuit are continuously tested for opens and shorts. The monitor looks for the Differential Pressure Feedback EGR circuit voltage to exceed the maximum or minimum allowable limits.

    The DTCs associated with this test are DTCs P1400 and P1401.
  1. The EGR vacuum regulator solenoid is continuously tested for opens and shorts. The monitor looks for an EGR Vacuum Regulator circuit voltage that is inconsistent with the EGR Vacuum Regulator circuit commanded output state.

    The DTC associated with this test is DTC P1409.
  1. The test for a stuck open EGR valve or EGR flow at idle is continuously performed whenever at idle (TP sensor indicating closed throttle). The monitor compares the Differential Pressure Feedback EGR circuit voltage at idle to the Differential Pressure Feedback EGR circuit voltage stored during key on engine off to determine if EGR flow is present at idle.

    The DTC associated with this test is DTC P0402.
  1. The differential pressure feedback EGR sensor upstream hose is tested once per drive cycle for disconnect and plugging. The test is performed with EGR valve closed and during a period of acceleration. The PCM will momentarily command the EGR valve closed. The monitor looks for the differential pressure feedback EGR sensor voltage to be inconsistent for a no flow voltage. A voltage increase or decrease during acceleration while the EGR valve is closed may indicate a fault with the signal hose during this test.

    The DTC associated with this test is DTC P1405.
  1. The EGR flow rate test is performed during a steady state when engine speed and load are moderate and EGR vacuum regulator duty cycle is high. The monitor compares the actual Differential Pressure Feedback EGR circuit voltage to a desired EGR flow voltage for that state to determine if EGR flow rate is acceptable or insufficient. This is a system test and may trigger a DTC for any fault causing the EGR system to fail.

    The DTC associated with this test is DTC P0401. DTC P1408 is similar to P0401 but performed during KOER Self-Test conditions.
  1. The MIL is activated after one of the above tests fails on two consecutive drive cycles.
egr vacuum solenoid - 0a01005.gif EGR Vacuum Regulator Solenoid The EGR vacuum regulator solenoid (Figure 88) is an electromagnetic device which is used to regulate the vacuum supply to the EGR valve. The solenoid contains a coil which magnetically controls the position of a disc to regulate the vacuum. As the duty cycle to the coil increases, the vacuum signal passed through the solenoid to the EGR valve also increases. Vacuum not directed to the EGR valve is vented through the solenoid vent to atmosphere. Note that at 0% duty cycle (no electrical signal applied), the EGR vacuum regulator solenoid allows some vacuum to pass, but not enough to open the EGR valve.

Exhaust Gas Recirculation (EGR) Vacuum Regulator Solenoid Removal and Installation
  1. Disconnect the battery ground cable (14301). For additional information, refer to Section 414-01 .
  1. Disconnect the vacuum hoses and the EVR solenoid electrical connector.
  1. Remove the two nuts and the EVR solenoid (9J459).
From the looks of the rubber mounting, I would say it's mounted on the cowl (firewall) on the passenger side in the engine compartment.

Sounds like you have a vacuum leak, a problem with the wiring, or a bad PCM. Check wiring for pinched, chafed, pierced, or broken wires. Make sure vacuum supply is good, and not collapsing when the vehicle is running. Beyond that, a trip to the dealer may be in order.

SOURCE: where can i find the timing marks on 1998 ford escort zx2 ?

Hello pamgolmon: My name is Roger and i will answer your question. The 2-0 dual cam engine is a interference engine. This means if the engine jumps time at the timing belt. It will bend the valves. As for the timing marks on the camshafts. Their are no marks to be located. To set the timing marks on this engine requires special tools. This makes it expensive for not only the do it yourself mechanic but also the repair shops also. If the valves were bent you must pull the head for the repairs also.
I know this is not the answer you were hoping for but it is the only answer to give. Please rate the quality of the answer as this way we know your answer was correct. Please just ask if you need further help. Thank You for using Fix Ya. Roger

go to www.gates.com on the lower right hand side under popular topics, click on timing belts, then on the left hand side click Parts Locator and Interchange, enter your cars info and the first page that comes up will show you a camera icon for a pic of how your belt is routed. The tensioner pulley is the one mounted on a silver arm, usually at the top. Hope this helps let me know.

Where is the egr solenoid located


EGR vacuum solenoid is located below your EGR valve. Center your self on the engine, look between the rear of the engine and your firewall. You can see your the top of you EGR valve, there will be a small vacuum hose connected to the top. Follow that small hose straight down from your EGR valve and it connects to the solenoid. You can see the solenoid better from beneath the car. May have an orange connector. Hope this helps.
