Laymans terms

This code means that the car's computer is having trouble understanding the amount of force or power being used. It's like when you try to guess how heavy something is, but your guess is way off.

Explanation

The control module performs self-tests to ensure all systems are functioning correctly. This code indicates a problem with the plausibility of the current torque value during these tests.

Technical description

The P16C1 code is set when the control module detects an inconsistency or implausibility in the torque monitoring system's current indicated value during its self-test. This could be due to a mismatch between expected and actual values, indicating a potential issue with the torque sensor or related components.

Symptoms

• Check Engine Light is on

• Reduced engine performance

• Unusual engine noises

Common Causes

• Faulty torque sensor

• Wiring issues in the torque monitoring circuit

• Malfunctioning control module

Glossary
