What is the P0318 Fault code? What does it all mean?
Modern vehicles often have an accelerometer sensor or rough road sensor that detects uneven roads and other adverse driving conditions. The vehicle may experience crankshaft position fluctuations and irregular engine speed when it is driven on off-road or rough roads. This could be interpreted by the powertrain control module (PCM), as an engine misfire or failure. This is made possible by rough road sensors. A P0318 code will be sent to the PCM if there is a problem with the circuit for rough road sensor “A”.
P0318 fault codes can be found on many vehicles, including Audi, Chevrolet and Dodge models.
Note: The description of the code can vary depending on the vehicle’s make and model. To determine the exact diagnosis and to learn how to fix it, consult the vehicle’s service manual.
What is the P0318 Fault Code?
Below are some reasons to set fault code P0318:
- – Defective road sensor
- – Broken wires can lead to bad path sensor “A”, rusty connectors, short circuit problems, or open circuit issues
- – Sensor on rough roads incorrectly placed
- – The PCM has become faulty or requires reprogramming
What are the symptoms for the P0318 fault code?
You may experience the following symptoms if your vehicle has the code P0318:
- – Illumination at the check engine lights
- – ABS and Traction Control Warning Lamps are now available
- – Problems with the Traction Control System
- – Concerns regarding the anti-lock brake system (ABS).
- – Problems with engine ignition
- Engine misfire
- – Engine hard start
How to Fix the P0318 Fault Code
It is essential to address all other codes in the memory before you can resolve fault code P0318. When repairing fault code P0318, the most common error is to replace the ABS speed sensors and crankshaft position sensors. This will not fix your problem. The problem must be diagnosed by a professional mechanic.
The following repairs may be able to resolve the P0318 fault code:
- Repairing damaged wires and connectors to fix bad road sensor “A”, circuit
- Replacing a defective rough road sensor
- – Reprogramming or replacing the PCM
How Serious Is the P0318 Fault Coding?
The P0318 fault code must be addressed immediately as it can affect your braking system. If you don’t want your vehicle to stop, your braking distance could increase, and your driving safety may be at risk.
