  • Scanned engine codes, found multiple stored faults. Fuel pressure sensor (P018B, P018C), misfires (P0303,P0304,P0313,P0316), catalyst efficiency (P0420) and engine temperature and cylinder head temperature correlation (P1026). Customer complains of the misfire, this will be diagnosed. Additional codes will require additional time. Started the engine and noticed misfire, scan data identifies as cylinder 3. Noticed what appears to be a new coil on the offending cylinder. Performed ignition component comparison, swapping the coil with 1 and the plug with 2. Started engine and misfire now moves to cylinder 2, condemning the spark plug. They read Ford but may have been replaced at some point. These vehicles have issues with coolant leaking into the combustion chamber. Warmed engine, pressure tested cooling system and let engine cool. Using boroscope, inspected inside the cylinder and no evidence of coolant found. Scan data shows abnormal fuel pressure and cylinder head readings. This will not cause an individual misfire but will continue to illuminate the engine light if not repaired.Additional diagnostic approved. Code P018 diagnosed first. Data shows erratic signal return. Disconnecting the plug causes a 5 volt return open, so reading it's a constant 108.7 psi. Tested for 5 volts and ground, present and steady. Low fuel pressure sensor has an internal defect and requires replacement. Next up is P1026 for the temperature sensors correlation. Data reveals no voltage return from the cylinder head temperature sensor. Disconnected the plug and verified 5 volt reference and ground are present. At operating temperature, typical resistance is 3k ohms. This sensor is reading 78 mega ohms, or 78,000,000. This reading is basically an open circuit. Cylinder head temperature sensor is defective and requires replacement. P0420, catalyst efficiency, is last. Warmed engine to operating temperature and monitored the sensors. The downstream sensor is mirroring the upstream, which indicates the converter is not burning the exhaust gases. The catalytic converter will have to be replaced. This is a federal emissions vehicle.
  • Test drove vehicle. Raised on lift and performed vehicle inspection. Filled out vehicle condition report and submitted to service advisor.
  • Replace RKE battery – per client request.
  • Removed and replaced wiper blades. Verified proper operation
  • Add cleaner to transmission. Test drive to verify operation and circulate cleaner. Use fluid exhnage machine to remove old fluid and add new. Add fluid conditioner and verify proper level. Test drive to verify proper operation.
  • Raised vehicle on lift. Removed rear wheels. Disassemble rear brakes. Resurface rotors. Add brake material conditioner. Lube rear brake hardware and brake pad backing plates. Installed new brake pads and brake pad hardware. Compressed caliper piston and installed caliper. Installed rear wheels and torqued to specification. Road tested vehicle to verify proper brake operation.
  • Inspect all hydraulic line and hoses. Inspect calipers and wheel cylinders if applicable. Inspect master cylinder and cap. Flush entire brake system including master cylinder, calipers, wheel cylinders until clean. Test drove to verify proper brake operation.
  • Remove the drive belt and pulley. Remove fasteners and water pump. Clean the mounting surface and install a new pump. Reassemble, test drive and inspect the repair.
  • Inspect hoses and clamps. Add cleaner to coolant and run through engine, radiator, and heater core. Installed coolant flush machine in-line to coolant system. Pulled vacuum on system to remove old coolant. Pushed 3 gallons of new coolant through cooling system. Add conditioner and sealant to system. Check thermostat and electric cooling fan operation. Test drive and verify proper operation of cooling system.
  • Remove the rear wheels and support the lower control arms. Remove fasteners and shocks. Swap over the mounts and install the new absorbers. Reassemble and test drive the veh
