Code P0716 Pontiac Description

The Input Speed Sensor (ISS) is a hall-effect type sensor. The ISS mounts to the control valve upper body assembly and connects to the control solenoid (w/body and TCM) valve assembly through a wire harness and connector. The sensor faces the 1-2-3-4 and 3-5-R clutch housing machined teeth surface. The sensor receives 8.3-9.3 volts on the Input/Output Speed Sensor (ISS/OSS) supply voltage circuit from the Transmission Control Module (TCM). As the 1-2-3-4 and 3-5-R clutch housing rotates, the sensor produces a signal frequency based on the machined surface of the 1-2-3-4 and 3-5-R clutch housing. This signal is transmitted through the ISS signal circuit to the control solenoid (w/body and TCM) valve assembly. The control solenoid (w/body and TCM) valve assembly uses the ISS signal to determine line pressure, transmission shift patterns, Torque Converter Clutch (TCC) slip speed and gear ratio.

Code P0716 indicates a problem with the transmission input or turbine speed sensor. The sensor's signal is out of range or inconsistent with expected values.

What are the common symptoms of code P0716 in a Pontiac?

Symptoms may include erratic shifting, delayed gear engagement, reduced fuel efficiency, transmission overheating, or the vehicle entering limp mode.

What causes the P0716 code to appear on a Pontiac?

Possible causes include a faulty input/turbine speed sensor, damaged wiring or connectors, transmission fluid issues, or internal transmission problems.

Can I drive my Pontiac with the P0716 code active?

Driving with this code is not recommended, as it can lead to further transmission damage or unsafe driving conditions due to erratic shifting.

How can I diagnose the P0716 code on a Pontiac?

Start by scanning the vehicle with an OBDII tool, inspecting the input speed sensor and its wiring for damage, and checking the transmission fluid level and condition.

What is the role of the transmission input/turbine speed sensor?

The sensor measures the rotational speed of the transmission's input shaft and sends this data to the engine control module to optimize shifting and performance.

How do I fix the P0716 code on my Pontiac?

Common fixes include replacing the input speed sensor, repairing damaged wiring or connectors, topping off or replacing transmission fluid, or addressing internal transmission issues.

How much does it cost to repair the P0716 code on a Pontiac?

The cost varies depending on the issue but typically ranges from $150 to $300 for sensor replacement, plus additional costs for labor or transmission repairs if needed.

Can low transmission fluid cause the P0716 code?

Yes, low or contaminated transmission fluid can affect the sensor's performance and trigger this code.

What tools are needed to troubleshoot the P0716 code on a Pontiac?

You'll need an OBDII scanner, a multimeter to test electrical connections, and possibly basic tools to access and replace the input speed sensor.
