Blocked fuel vapor hose between EVAP canister purge valve and FTP sensor.

P1443 Evaporative Emission Control System Control ValveThe Evaporative Emission Control System monitors the fuel vapor flow between the engine intake manifold and the EVAP canister. The system failure occurs when a leak or blockage between the intake manifold, the EVAP canister purge valve and the EVAP canister is detected by the PCM.
Code P1443 Possible Causes:
- Pinched, blocked or plugged fuel vapor tubes/hoses (except between fuel tank and EVAP canister)
- Damaged EVAP canister
- Disconnected, cracked or cut fuel vapor tubes/hoses (except between fuel tank and EVAP canister)
On the 1988 XR7 the Ford diagnostic connector is located under the hood and just ahead of the right front strut tower. It's not the familiar looking OBD-II 16 pin connector but is the Ford style two part connector consisting of one single wire with a female spade type connector and another odd shaped connector with 5 or 6 female spade connectors in it. The typical auto parts store OBD-II reader won't work to read codes on this one, instead you need someone with an older tester to see what is happening and the data available from the system is quite limited also. Hope this helps and good luck!
NOTE Enter this Pinpoint Test only when directed here.
The use of a soap solution, such as SNOOP, around the fuel filler cap or the use of the hydrocarbon emission analyzer to determine an evaporative emission system leak is not recommended. The mandatory Rotunda Evaporative Emission System Leak Tester for OBD II (including the ultra-sonic tester) is the only device to be used at this time for evaporative emission system leak detection.
This Pinpoint Test is intended to diagnose the following:
Ok i have the same make and model car.And had same problem but i was only needing new hoses. thwe code reader will not tell you if they are bad you just have to check this. The purge valve and canister is located under hood on passenger side behind bumper. look behind the light through the openings. You have to raise car up and do the repairs from under the bottom of the bumper.On passenger side under hood above the wheel fender and between the engine you will see a emmision line about the size of a pencil leads to the purge valve. the valve cost about $18.00 and canister cost around $75.00 at auto zone. The canister is the square box and sometimes you can take apart and clean it and put back together and it should work fine.
