Issue:
Some X-TYPE vehicle within the above VIN range may experience driveability issues along with an illuminated MIL.
DTCs that relate to the 5-volt supply circuits for the sensors may also be present.
Action:
On a customer complaint basis only, if the vehicle is suffering from driveability issues and any DTCs relating to the 5-volt sensor supply circuits are logged, record the logged DTCs for future reference and follow the workshop procedure outlined below.

If damage to wiring has been identified, disconnect electrical connector and continue from step 7. If there is no damage to wiring, disconnect electrical connector and continue from step 16.
7. Displace anti back-out device from air conditioning pressure switch electrical connector.
8. Displace cover from rear of air conditioning pressure switch electrical connector.
9. Displace chafed wire from air conditioning pressure switch electrical connector.
10. Cut heat shrink sleeve from harness repair kit to appropriate length to cover chafe in wire insulation.
Note:
Refer to harness repair guide to determine the correct diameter heat shrink sleeve required.
11. Install heat shrink sleeve over chafed wire.
