P0716 Input/Turbine Speed Sensor Circuit Range/Performance

Check Engine Light

P0716 code definition

The P0716 code indicates that the car’s computer has received an input signal from the engine speed sensor that is incorrect in some way. Without accurate input information, the computer will be unable to create the right shifting strategy for the transmission.

What the P0716 code means

In order for an automatic transmission to shift properly, the car’s computer must know the vehicle’s engine speed. If the input signal from the input speed sensor is erratic or incorrect, then the computer will lack information crucial for shifting correctly for current conditions. If the input speed changes radically, or exceeds the output speed, then the PCM will set the P0716 code.

What causes the P0716 code?

Several possible causes exist for the P0716 code. They include the following:

  • Failed input speed sensor
  • Failed output speed sensor
  • Damage to a sensor’s wiring harness
  • Corroded connections at the input or output speed sensor
  • Faulty transmission shift solenoid
  • Failed engine temperature sensor
  • Low transmission fluid
  • Dirty/contaminated transmission fluid that does not flow properly
  • Failed PCM (rare)

What are the symptoms of the P0716 code?

Symptoms of the P0716 code can vary greatly depending on the underlying cause, and in some cases, there may be no symptoms. They include the following:

  • Engine stalling when coming to a stop
  • Engine misfires
  • Harsh shifting
  • Failure to shift
  • Engine stalling
  • Engine hesitation
  • Speedometer fluctuations
  • Speedometer inoperable
  • Check Engine light on

How does a mechanic diagnose the P0716 code?

First, the mechanic will connect an OBD II scanner to the car and verify the code or codes. These codes will then be cleared, and the vehicle test driven to verify that the codes reset, and that the mechanic is able to duplicate the symptoms stated by the driver.

The mechanic should also check the level and condition of the transmission fluid to rule out low fluid level and fluid contamination as the culprit.

If the code resets, the mechanic will check the reference voltage and ground signals at the input speed sensor. If either is open, the mechanic will check for continuity, and repair or replace any damaged wiring or circuits. If there is no open, the mechanic will have to test all the wiring and circuits, as well as all related sensors and solenoids to determine the underlying cause.

Common mistakes when diagnosing the P0716 code

The most common mistake here is replacing the speed sensor when it is not actually the problem. A full diagnosis must be made in order to rule out all possible causes, including contaminated transmission fluid, wiring harness damage and more. The initial trouble code should be troubleshot first, and then each following code in order of occurrence.

How serious is the P0716 code?

The P0716 code is very serious, as it can affect vehicle drivability and even leave you stranded in the road with a stalled engine when coming to a stop. It is very important to have this code diagnosed as soon as possible.

What repairs can fix the P0716 code?

Repairs for the P0716 code vary greatly depending on the underlying cause. They can include the following:

  • Replacing a failed input speed sensor
  • Replacing a failed output speed sensor
  • Rebuilding a damaged transmission (indicated by finings and contamination in the transmission fluid)
  • Repairing or replacing damaged wiring
  • Repairing corroded connections
  • Replacing failed circuitry

Additional comments for consideration regarding the P0716 code

Diagnosing the P0716 code can be an involved and lengthy process due to the number of potential causes. It is essential that a mechanic eliminates all possibilities to prevent the problem from reoccurring immediately.
