P0716: Input/Turbine Speed Sensor A Circuit Range/Performance
The P0716 code indicates that the Powertrain Control Module (PCM) has detected an abnormal signal from the input/turbine speed sensor (sensor A) in the transmission. This sensor monitors the rotational speed of the turbine shaft inside the torque converter. The PCM uses this data to control shift timing and torque converter lockup. A range/performance fault means the signal is erratic, out of expected range, or inconsistent with other sensor readings, often due to sensor damage, wiring issues, or mechanical problems within the transmission.
01. Most Common Causes
- Faulty input/turbine speed sensor
- Damaged or corroded wiring/connectors to the sensor
- Low transmission fluid level or contaminated fluid
- Internal transmission mechanical failure (e.g., worn torque converter)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Harsh or erratic shifting
- Transmission slipping or delayed engagement
- Reduced fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Inspect transmission fluid level and condition; top off or replace if necessary.
Step 3: Visually check the sensor and wiring for damage, corrosion, or loose connections.
Step 4: Test sensor resistance and voltage output with a multimeter per manufacturer specs.
Step 5: If sensor and wiring are okay, perform a transmission mechanical inspection (e.g., torque converter operation).

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as the transmission may shift erratically or slip, potentially causing further damage. Drive only to a repair shop.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for a sensor replacement, but could be higher if wiring repairs or transmission work is needed.
