So, what does Harley code p1353 stand for? Well, it indicates your Harley Davidson has some issues with the front cylinder combustion and the wiring system. The problems may include a Faulty Spark Plug, plug gap, loose plug tip where the wire joins on, and even bad wiring on the injectors near the plug. To resolve the issues you have to look at the wiring system.
Ignoring this issue can cause significant damage to your bike and result in costly repairs. But don’t worry! we will discuss all the possible causes and solutions to the Harley code P1353. So, keep on reading!
Harley Code P1353 : Problems and Fixes
First, have all the possible causes and fixes looked at a glance.
| No. | Problems | Fixes |
|---|---|---|
| 1. | Faulty Spark Plug | Inspect ignition coil and spark plug wire |
| 2. | Plug gap/Loose plug tip | Tighten the wires |
| 3. | Bad wiring on the injectors | Replace the injector |
| 4. | Faulty crank position sensor | Replace the crank sensor |
Keep in mind that the following are some common issues. Additional difficulties that you can face are potential. If you detect any further problems, take appropriate action.
Problem 1: Faulty Spark Plug
The spark plug is an essential component of the ignition system. It delivers the spark required to ignite the fuel and air mixture in the combustion chamber. A faulty spark plug can cause the P1353 code to appear on the diagnostic system.
Solution:
If the P1353 code is caused by a faulty spark plug, several steps can be taken to resolve the issue:
- Step 1: Inspect the Spark Plug
The first step is to inspect the spark plug for any signs of damage, wear, or fouling. Check the condition of the gap, and the porcelain insulator. If the spark plug is damaged, or worn out, it will need to be replaced.
- Step 2: Replace the Spark Plug if Required
If the spark plug is found to be faulty, replace it with a new one. Be sure to use the correct spark plug for your Harley model.
- Step 3: Check the Spark Plug Wire
Inspect the spark plug wire for any visible signs of damage or wear. If the wire is damaged, or worn out, it can cause a weak spark or a complete loss of spark, which may result in the P1353 code. If the wire is damaged, it will need to be replaced.
- Step 4: Check the Ignition Coil
Inspect the ignition coil for any signs of damage or wear. Check the coil for any cracks or other visible signs of damage. If the coil is damaged, it can cause a weak spark or a complete loss of spark. Replace it if requires.
Problem 2: plug gap/Loose plug tip
Faulty spark plugs can be one of the causes of the P1353 code. Even a slight gap in the spark plug or loose plug tip can cause the ignition system to malfunction. So, it is always important to have it looked at carefully.
Solution:
Below is some steps to identify and solve this issue:
- Step 1: Check the Spark Plug Gap
The spark plug gap is the distance between the center and the ground electrode of the spark plug. The correct gap is important for the proper functioning of the ignition system. A range of 0.40cm can be an ideal gap.
You can check the gap using a feeler gauge. If the gap is incorrect, it can be adjusted by carefully bending the ground electrode. Be careful not to damage the electrode while bending. The electrode may enter the cylinder if it is broken off. It could harm the valves or leave a damaged scrape on the cylinder.
- Step 2 : Clean the Spark Plug
If it looks in dirty condition, the spark plugs then can be cleaned. In the contact point, you may see some damaged signs which is quite whitish. Clean the spark plug with alcohol if it looks dirty.
- Step 3: Check the Tightness of the Spark Plug
Ensure that the spark plug is tightened to the recommended torque specifications. A loose spark plug can cause misfires and other ignition problems.
However, be careful not to overtighten the spark plug, as this can damage the threads or the insulator.
Problem 3: Bad Wiring in the Injectors
Bad wiring on the injectors can also cause the P1353 code to appear on the diagnostic system. The wiring that connects the injectors to the engine’s computer can become damaged or worn over time, causing problems with the fuel delivery system.
Solution:
Here are some possible solutions if bad wiring on the injectors is the cause of the P1353 code:
- Check the Connections: Inspect the connectors that connect the wiring to the injectors and the engine’s computer. Make sure they are clean, free of debris, and properly connected. If they are dirty or corroded, clean them with a wire brush and reconnect them.
- Test the Wiring: Use a multimeter to test the wiring for continuity and resistance. This can help you identify any problems with the wiring that may not be visible to the naked eye. If the wiring fails the continuity or resistance test, replace the wiring.
Problem 4 : Faulty Crank Position Sensor
The crankshaft position sensor is responsible for sending signals to the engine control module about the crankshaft’s position and speed. If it gets clogged, it may cause the bike to stop suddenly as it can cause the engine to backfire.
As crankshaft position sensors are quite related to the Harley code p1353 problems component, you may have a look at it too.
Solution
The following steps can be helpful in such a situation :
- Step 1: To prevent electrical shorts, disconnect the negative battery cable.
- Step 2: Find the engine’s crankshaft sensor, which is often located close to the harmonic balancer or timing cover.
- Step 3: Unplug the electrical connector from the sensor.
- Step 4: Remove the mounting bolts to pull the sensor out of its mount.
- Step 5: While installing the replacement sensor, clean the area surrounding the sensor mount to ensure a tight seal.
- Step 6: Install the replacement sensor into the mount.
- Step 7: Tighten the mounting bolts.
- Step 8: Reconnect the electrical connector to the sensor.
Following the measures accurately, you can replace the crankshaft position sensor of your Harley Davidson.
Therefore, these are some of the most typical Harley-Davidson difficulties that might result in the code p1353. It can also be represented by other difficulties as well.
FAQs
We know you’re here to know a little more. Don’t go away!
Q: Can a bad ground wire cause the P1353 code to appear?
A bad ground wire can cause a variety of issues with the engine and electrical system. But it is unlikely to specifically cause the P1353 code to appear. However, it is always good to monitor the ground connections in the engine and electrical system to ensure they are functioning correctly.
Q: What are the recommendations to ride my Harley Davidson with a P1353 code?
It is not recommended to ride your motorcycle with a P1353 code as it can cause the engine to misfire and it can damage the engine components. It is best to address the issue as soon as possible and fix the problem before riding your motorcycle again.
Q: Can I diagnose and fix a P1353 code myself?
If you have the necessary knowledge and tools, you can diagnose and fix a P1353 code yourself. However, it is recommended to seek professional help if you are not confident in your abilities. Because an incorrect diagnosis or repair can cause further damage to your motorcycle.
Conclusion
All in all, if you encounter a Harley code P1353 in Harley-Davidson diagnostic system, it is crucial to address the issue promptly. It has to be done to prevent further damage to your bike. A thorough inspection of the spark plug, plug wire, ignition coil, and crankshaft position sensor can help identify and resolve most of the underlying causes.
