Where's the egr vacuum solenoid located on my 2002 Ford Escort ZX2? Can I see from the top of the engine?
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.
The DTCs associated with this test are DTCs P1400 and P1401.
The DTC associated with this test is DTC P1409.
The DTC associated with this test is DTC P0402.
The DTC associated with this test is DTC P1405.
The DTC associated with this test is DTC P0401. DTC P1408 is similar to P0401 but performed during KOER Self-Test conditions.
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.

Removal and Installation
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.

cam shaft timing marks on back of cams ,two slots ,use a flat piece of metal to align .remove no1 spark plug and drop long thin screwdriver down it to bring piston just below tdc,then align cams so both cams are on the rock (valves closed) with knob on back cam aligning with pick up sensor left side between lobes.then bring piston up to tdc and fit belt.turn engine over twice with socket on bottom pulley to make sure no valves clear pistons.Remember to remove flat edge from back of cams i didnt last time and bent my home made tool

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.

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.
