Can a bad speed sensor stop a car from starting?
A bad crankshaft or camshaft position sensor may prevent the car from starting. Some vehicles have redundant sensors that allow the vehicle to start and run even if one speed sensor is bad. In these cases, you are likely to see a check engine light with a code that should give you a clue which speed sensor is faulty.
What are the different types of transmission sensors?
There are two main types of transmission speed sensors: the input shaft speed sensor and output shaft speed sensor. An input shaft speed sensor measures the speed of the input shaft and torque converter, which matches the speed of the engine.
What are the symtoms of a bad transmission speed sensor?
- your speedometer may not work.
- the transmission control unit (TCU) may have a hard time knowing when or how quickly to shift gears.
- No Cruise Control
Why is a speed sensor on transmission malfunction?
A car’s transmission speed sensor also allows the vehicle to keep track of the distance it has travelled: for every 40,000 magnetic pulses, the odometer reading increases by one mile. What Can Go Wrong? A transmission speed sensor can malfunction for a variety of reasons: Corrosion of the component; Loose or disconnected wires
What does a bad speed sensor do?
A bad speed sensor most often affects the shifting of the automatic transmission. However, in cars with an onboard computer, the sensor also affects the ABS system , speedometer, cruise control and power steering. Proper diagnosis and repair is essential for safe operation of the car.
How does a speed sensor go bad?
A broken or damaged magnet on the motor can result in a bad speed sensor. If this is replaced with a new magnet, the speed sensor will begin to function properly. Alternatively, the magnet could have just come loose.
