What does the P0302 code mean?

The P0320 code is a generic trouble code that indicates a malfunction in the ignition/distributor engine speed input circuit. This circuit is responsible for monitoring the engine speed and providing feedback to the vehicle’s computer system. When a problem occurs in this circuit, the computer system will trigger the P0320 code and alert the driver of the issue.

The engine speed sensor can be somewhat confusing since many automotive brands like Lexus actually place it on the transmission. This way it can properly measure the output speed and report this information to the engine control module which then proceeds by calculating combustion metrics.

What causes the P0302 code?

While the code may direct you in a way to think that the engine speed sensor has gone wrong, there are other potential reasons behind this issue. Our team has prepared a complete guide to get you on the right track and help you figure it out as soon as possible:

Faulty crankshaft position sensor

The crankshaft position sensor is responsible for monitoring the rotational speed and position of the crankshaft. A faulty sensor can cause the P0320 code to appear and may also result in engine misfires, stalling, or hesitation.

Damaged or corroded wiring

Wiring damage or corrosion can interrupt the transmission of signals between the crankshaft position sensor and the vehicle’s computer system. This can cause the P0320 code to appear and may also lead to other electrical issues in the vehicle.

Failed ignition system

A failed ignition system can cause the P0320 code to appear. This can occur due to a variety of issues, including faulty spark plugs, damaged ignition coils, or other issues that prevent the engine from igniting properly.

Other issues

Other potential causes of the P0320 code include issues with the timing belt or chain, a malfunctioning engine control module (ECM), or a damaged camshaft position sensor.

Which car models does the P0320 code affect the most?

The P0320 code can affect a wide range of car models. However, some models are more prone to experiencing this issue than others. Vehicles that are most commonly affected by the P0320 code include:

• Dodge RAM: The Ram is a popular pickup truck that may experience issues with the crankshaft position sensor, leading to the P0320 code.
• Jeep Grand Cherokee: The Grand Cherokee is a midsize SUV that could encounter issues with the camshaft position sensor, resulting in the P0320 code.
• Honda Civic: The Civic is a compact car that may experience issues with the crankshaft position sensor or wiring harness, leading to the P0320 code.
• Toyota Camry: The Camry is a midsize sedan that may encounter issues with the crankshaft position sensor or wiring harness, resulting in the P0320 code.

How to diagnose the P0320 code

Diagnosing the P0320 code requires specialized tools and equipment. If you don’t have expert knowledge on diagnosing the main reasons behind the code like a professional mechanic, you can still apply a few methods that don’t require as many tools. The following steps can help drivers identify the issue:

Scan for trouble codes

The first step in diagnosing the P0320 code is to scan the vehicle’s computer system for trouble codes. This can be done using an OBD-II scanner or other diagnostic tool, but you can also find an affordable scanner tool that you can pick up for as little as $20 to diagnose the code.

Inspect the crankshaft position sensor

Inspect the crankshaft position sensor for any visible damage or signs of wear. This sensor is typically located near the bottom of the engine, near the crankshaft.

Check wiring and connections

Check the wiring and connections leading to the crankshaft position sensor. Look for any signs of damage or corrosion that may be interrupting the signal transmission.

Check Ignition System Components

Inspect the spark plugs, ignition coils, and other ignition system components for issues that may be causing the P0320 code to appear.

How to fix the P0320 code

Fixing the P0320 code typically involves addressing the underlying issue that is causing the code to appear. Some potential fixes include:

Replacing the crankshaft position sensor

If the crankshaft position sensor is faulty, it will need to be replaced. This can typically be done by a professional mechanic or experienced DIYer.

Repairing or replacing wiring

If wiring damage or corrosion is causing the issue, it will need to be repaired or replaced. This may involve replacing the entire wiring harness or simply repairing the damaged wires.

Replacing ignition system components

If the ignition system is causing the P0320 code to appear, components such as spark plugs or ignition coils may need to be replaced.

It’s important to note that the cost of repairing the P0320 code can vary depending on the underlying issue and the make and model of the vehicle. Some repairs may be relatively inexpensive, while others may require significant investment.

How to prevent the P0320 code

Preventing the P0320 code from appearing requires regular maintenance and attention to your vehicle’s ignition system. Here are a few tips to help prevent this issue:

• Regular maintenance
• Dealing with any signs of code-related warning lights promptly
• Checking the ignition system and timely replacing spark plugs

Performing regular maintenance on your vehicle, such as oil changes and tune-ups, can help prevent issues with the ignition system. All this has to do with your car’s engine so it’s not advised to try and deal with it yourself.

Upon any signs of damage or problems related to the code, you should at least consult a professional mechanic on the next steps you can take.

Our take

Ultimately, dealing with the code P0320 is easier than you may expect if you know what to look for. You can always rely on professional help if you are unsure as to how the problem may be fixed, but we also hope this guide has shed some light on ways of dealing with it yourself, especially when it comes to future code prevention.
