The code P145C on your vehicle’s scanning tool indicates a malfunction in EVAP (Evaporative Emission Control System). This system keeps the gasoline vapors from getting inside the fuel tank or system.
A defective purge valve, seal, or O-rings can damage the EVAP and lead to inappropriate pressure in the fuel tank and faulty electric connection.
Thus, the code appears. The repair codes from Honda are really helpful. It helps you take better care of your car.
However, much confusion revolves around− what does P145C code mean. Stay with us to learn everything about it!
P145C – EVAP System Purge Flow Malfunction
Code P145C Meaning for Different Brands
The meaning of this code might indicate the fuel tank issues on average. But when you specify a brand, the answer would be more distinct. Have a look −
- Honda– Range or performance issues in the sensor of the fuel tank pressure
- Ford– Malfunction in fan function section
- Acura– Range or performance issues in the sensor of the fuel tank pressure
- Mercury– Malfunction in fan function section
- Lincoln– Malfunction in fan function section
Reasons Why P145C Appears
P145C primarily appears when the sensor of the fuel tank doesn’t work appropriately. This sensor determines and ensures the correct pressure for the fuel tank.
If the sensor isn’t working properly, a bunch of problems can occur, which will make the scanner show the P145C code. These are −
- Incorrect signals from the fuel tank sensor
- Open or extorted harness of the sensor
- Insufficient electric flow
All these disturb the fuel economy and cause more emissions. This is responsible for making the EVAP system go wrong. Eventually, your scanner shows the code.

Note: whenever your car goes through a code P145C situation, the engine light (engine service indicator) will show up.
After seeing the sign, you can inspect your car with your own scanning tool if you have one. Otherwise, you would need to turn to a professional.
How Do I Diagnose Code P145C?
Although we’ve mentioned the reasons which bring this code, pointing out the exact problem might need to be clarified.
So, we would like to specify the territories you need to check to diagnose the main problem.
- Check the connectors and wiring harnesses around the fuel tank and engine.
- See if any of the sensors or fan function components have been damaged.
- Components connected to fuel efficiency should be checked as well. Such as oil filters, spark plugs, air filters, fuel injectors, purge valves, O-rings, etc.
- Inspect the connector’s pins; they can’t be broken, corroded, or bent.
How to Fix Code P145C?
The fixes vary depending on the problem your vehicle has. So, first, you need to find it out as suggested above. Then you can fix them accordingly.
Resetting Inappropriate Sensor Signal
Faulty sensors can cause poor fuel efficiency. And it’s one of the primary reasons why P145C shows up.
For resetting the sensor, long press the Odo button. After 2 seconds, the Odometer will show ‘1’, which means the system is starting to reset.
Following this, the fuel gauge will reset. Release the button once the Odometer gets back to the starting phase.
Now check the sensors; if they still seem faulty, replace them with a professional.
Fixing Wiring Harness
Fixing the problems with wiring harnesses is very costly. Moreover, they might appear after a few days all over again. So, replacing it is the right thing to do.
If you find the connectors problematic, consider tightening them. Then reconnect the hoses if required. Replace the broken or damaged connector pins as well.
Often problems in some particular components can cause fuel inefficiency. So, consider checking them and replacing the damaged components.
Damages in oxygen sensors, spark plugs, air filters, oil filters, fan function components, and fuel injectors are likely to interrupt fuel efficiency.
Final Fix to All of the Problems
No matter why the P145C has appeared, after fixing the problem, you need to clear the code on your tool. Now reset it and scan again; if you’ve fixed the exact problem, the code won’t appear anymore.
Frequently Asked Questions
The cost varies depending on your area and your vehicle’s model, engine, and overall condition. It will be the cost of 1 hour of labor. Most automobile servicing shops will charge around $75 to $ 150 every hour.
Apart from the routine checks, you should go with it when the engine light appears without any obvious reason. Besides, poor fuel efficiency can work as a sign too.
Yes, it can. This code appears depending on many factors. Problems with engine components can be responsible for this as well.
Although vehicle problems and maintenance factors are nothing new, the warning system with codes is! Many depreciate this idea.
But we believe understanding the codes is very simple. Moreover, the codes help us maintain and keep our vehicles in better condition. Judging “what does P145C code mean?” has already proved it.
The manual will tell you about all the signs and codes as well. Go through it to be on the safe side.
