Defect
ON CERTAIN PASSENGER VEHICLES, THE FUEL PRESSURE SENSOR LOCATED ON THE LEFT END OF THE FUEL RAIL MAY, AT TIMES, TRANSMIT INCORRECT SIGNAL REGARDING THE FUEL PRESSURE TO THE ENGINE CONTROL MODULE. IF THE SIGNAL IS OUTSIDE OF THE PRE-PROGRAMMED ALLOWABLE LIMITS, A DIAGNOSTIC TROUBLE CODE MAY BE SET AND THE CHECK ENGINE LIGHT WILL COME ON. THE SOLDERED JOINTS ON THE CIRCUIT BOARD OF THE FUEL PRESSURE SENSOR MAY CRACK DUE TO TEMPERATURE CHANGES AND EXCESSIVE VIBRATIONS.
Consequence
MISFIRE MAY OCCUR DURING DRIVING THAT, IN TURN, WILL REDUCE THE ENGINE TORQUE AND IN THE WORST CASE SCENARIO, THE ENGINE MAY STALL WITHOUT WARNING. IN CERTAIN TRAFFIC SITUATIONS THIS COULD CAUSE AN UNSAFE SITUATION AND POSSIBLY A CRASH.
Remedy
DEALERS WILL REPLACE THE FUEL PRESSURE SENSOR FREE OF CHARGE. THE RECALL BEGAN ON JUNE 29, 2007. OWNERS MAY CONTACT VOLVO AT 1-800-458-1552.
