NHTSA Complaint #10347331 — 2002 TOYOTA CAMRY

ONE OF TWO ELECTRONIC ACCELERATOR POSITION SENSORS MALFUNCTIONED ON MY 2002 TOYOTA CAMRY. I EXPERIENCED A SLUGGISH RESPONSE TO PEDAL ACTION (I.E. I HAD TO PUSH THE PEDAL FARTHER THAN NORMAL TO GAIN ANY ACCELERATION - CHECK ENGINE LIGHT WAS ALSO ILLUMINATED). I IMMEDIATELY DROVE TO MY MECHANIC'S SHOP FOR EVALUATION AND REPAIR. AFTER RUNNING DIAGNOSTICS, HE DETERMINED THAT THE SENSOR HAD MALFUNCTIONED AND ADVISED ME NOT TO DRIVE THE CAR ANY FURTHER UNTIL IT WAS REPAIRED. AS I UNDERSTAND IT, FROM MY MECHANIC'S EXPLANATION, THE SENSOR DETERMINES THE POSITION OF THE ACCELERATOR AND SENDS A REQUEST FOR ACCELERATION AS A VOLTAGE RANGING FROM 0-5V, WHERE 0V IS NO ACCELERATION AND 5V IS FULL-THROTTLE. THROUGH FURTHER TESTING, HE DETERMINED THAT THE SENSOR THAT HAD MALFUNCTIONED WAS READING 5V. I FIND IT VERY CONCERNING THAT IN THE EVENT OF FAILURE THE SENSOR DOES NOT "FAIL SAFE" (I.E. FAIL TO 0V, RATHER THAN 5V). THE TECHNICIAN EXPLAINED THAT THE SECOND SENSOR WAS THERE AS A SAFETY REDUNDANCY, BUT EITHER WAY, "FAIL SAFE" IS ONE OF THE MOST BASIC DESIGN CONCEPTS IN AN APPLICATION WHERE SAFETY IS CRITICAL AS IS THE CASE HERE. IN MY CONVERSATION WITH TOYOTA, THEY WOULD NOT STAND BEHIND THE PART (MY WARRANTY HAD EXPIRED AND IT WAS NOT ON RECALL), NOR COULD THEY GIVE ME ANY ASSURANCE THAT THE REPLACEMENT PART HAD BEEN REDESIGNED IN SUCH A WAY THAT IT WOULD "FAIL SAFE." I AM A WIFE, MOTHER OF TWO SMALL CHILDREN, AND THE PRIMARY INCOME GENERATOR FOR OUR FAMILY. I DO NOT FEEL GOOD ABOUT WHAT I NOW KNOW ABOUT THE SAFETY OF MY CAR AND DO NOT FEEL THAT TOYOTA TOOK MY CONCERNS TO HEART. I WOULD APPRECIATE ANYTHING YOU COULD DO TO HELP. I SUSPECT I MAY NOT BE THE ONLY ONE TO EXPERIENCE THIS SAFETY FAILURE. *TR
