Disconnect the vapor line at the charcoal canister that comes from the liquid vapor separator and goes to the charcoal canister. See if the fuel tank can be easily filled then. 2. If the fuel tank can easily be filled with the vapor line removed from the charcoal canister, reconnect the vapor line and remove the other lines from the charcoal canister and see if the fuel tank can be easily filled. 3. If the fuel tank is once again difficult to fill, replace the charcoal canister. 4. If disconnecting the vapor line at the charcoal canister does NOT make the fuel tank easy to fill, then disconnect the vapor line from the liquid vapor separator at the fuel tank in case the vapor line is plugged/restricted.… Read More
A) Installation of the magnetic sensor (gauge) A-242 B) Installation of the speed sensor A-246 C) Installation of the RPM amplifying A-451 D) Installation of the ALFANO
A) Installation of the magnetic sensor (gauge) A-242 – If the sensor doesn’t start to the passage on the magnetic field, use one or several spacers to bring the sensor closer to the ground. – When fixing the cable with nylon tighten-cables, take care to move this one most possible away of the exhaust.
B) Installation of the speed sensor A-246 – Fix the magnetic support (supplied) on one of the arms of the disc brake support with a nylon tighten-cable (see photos). Fix it on the narrowest part of the arm. – With a scorer, draw a feature on the mudguard in front of the magnetic support.- In this case, install the speed sensor to « 90° ». – Put down the mudguard and fix the speed sensor and its cable with nylon tighten-cables.… Read More

Tests/Procedures: 1. Check the right side (passenger side) Intake Valve Timing Control Position (IVTCP) sensor for 12 volts on the Black/White wire. 2. Check the IVTCP sensor for a good ground on the Black wire. 3. Scope the Yellow/Green signal wire and look for a square wave signal of around 8 volts. Check the pattern of the right side sensor and if unsure of the pattern, compare it to the left bank sensor. Potential Causes: IVTCP Sensor Wiring — IVTCP sensor wiring/connection. Tech Tips: This code is for the right (passenger) bank IVTCP Sensor or sensor circuit. The right and left bank sensors can be swapped from side to side to see if the code will follow the sensor.… Read More
