Oh no! Your car’s dashboard has lit up like a Christmas tree, and now you’re staring at a strange code: P0202. Don’t panic! At First Auto Centre, we’re here to explain what this means in plain English and how we can sort it for you. As trusted car specialists in your local area, we deal with the P0202 fault code regularly and know exactly what to do when it pops up on your dashboard.
The Basics: What Does P0202 Actually Mean?
Let’s break this down into bite-sized chunks. The P0202 fault code is basically your car’s way of saying, “Hey, there’s something wrong with my second cylinder’s fuel injector!”
Here’s what each part of the code means:
P = Powertrain (this relates to your engine, transmission, and related bits)
0 = It’s a standard code (the same across different car makes)
2 = Fuel and air metering
02 = Injector Circuit Malfunction, Cylinder 2
Put simply, your car’s computer thinks the second cylinder isn’t getting the right amount of fuel because something’s up with the injector.
Why Should You Care About This Fault Code?
Well, here’s the thing – ignoring a P0202 code can lead to:
Your car using too much fuel (bad for your wallet!)
Poor engine performance (that sluggish feeling when you press the accelerator)
Potential damage to your catalytic converter (a very expensive part to replace)
Failing your MOT test due to emissions problems
Contamination of your engine oil, requiring an early oil and filter change
According to research from the Society of Motor Manufacturers and Traders, problems with fuel injectors can increase your car’s emissions by up to 30%. That’s not good for the environment or your chances of passing your next MOT testing session! It’s also worth noting that repair costs can vary depending on how long you’ve left the problem unaddressed.
What Causes a P0202 Fault Code?
There are several culprits that might be causing this code to appear:
Possible Cause
Likelihood
Complexity to Fix
Faulty fuel injector
Very High
Moderate
Damaged wiring to the injector
High
Moderate
ECU (engine computer) issues
Low
Complex
Fuel pressure problems
Moderate
Varies
Contaminated fuel
Low
Simple
The most common cause is simply a worn-out or clogged fuel injector. Fuel injectors work incredibly hard, opening and closing many times per second to spray precisely the right amount of fuel into your engine. Over time, they can get gummed up or just wear out.
The Symptoms: How to Tell If You Have a P0202 Problem
Even before your check engine light comes on, you might notice:
Your car feels “jerky” when accelerating
The engine idles roughly (it feels uneven when you’re stopped at lights)
Strange noises from the engine
Reduced fuel economy (you’re visiting the petrol station more often)
A smell of petrol from the exhaust
If you’ve noticed any of these symptoms, it’s time to book in for car diagnostics to get to the bottom of the issue.
How We Diagnose P0202 at First Auto Centre

We connect our professional diagnostic equipment to confirm the code
We visually inspect the wiring and connectors to the cylinder 2 injector
We use specialised testing equipment to check if the injector is functioning properly
We examine fuel pressure and quality
We check your car’s overall condition, including engine oil levels
If necessary, we test the signals from the engine’s computer
The process might vary depending on your vehicle manufacturer specifications, but our team is trained across all major makes and models. According to the Institute of the Motor Industry, proper diagnostic procedures can reduce repair costs by up to 40% by avoiding unnecessary part replacements. That’s why our diagnostic and repairs service is so thorough!
How We Fix P0202 Problems
Once we’ve figured out exactly what’s causing your P0202 code, we’ll get it sorted. Here are the common fixes:
If It’s a Faulty Injector:
We’ll either clean the injector using specialised equipment or replace it if cleaning won’t do the trick. Our car repairs team has access to quality parts that match or exceed the specifications of your original injectors.
If It’s Wiring Issues:
Our technicians will repair or replace the damaged wiring and connectors, making sure everything is properly insulated and secured.
If It’s Fuel Quality:

The Importance of Regular Servicing in Preventing P0202
As the saying goes, prevention is better than cure! Regular servicing with a full car service can help prevent P0202 and other fault codes from appearing in the first place. When your car service due date approaches, don’t ignore it – it could save you from dealing with annoying fault codes later!
When you book a car service with us, our car specialists will:
Replace fuel filters that can prevent debris from reaching your injectors
Change your oil and filter to keep your engine running smoothly
Check the condition of your fuel system
Use fuel additives to clean injectors when appropriate
Check the electrical systems that control your injectors
Different types of car service will tackle different aspects of maintenance, but all contribute to preventing issues like the P0202 fault code. The UK Automotive Aftermarket Association suggests that regular servicing can reduce the risk of injector-related problems by up to 70%. That’s a massive difference for your wallet and peace of mind!
Our servicing pricing is transparent and competitive, so there’s no excuse to skip servicing your car regularly. Your future self will thank you!
DIY vs Professional Repair: What You Need to Know
Now, we know what you’re thinking – “Can’t I just fix this myself and save some cash?”
While there are plenty of YouTube videos claiming you can sort a P0202 code with a bit of injector cleaner from the local auto shop, here’s the honest truth:
Modern cars are incredibly complex. The days when your dad could fix everything with a spanner and some WD-40 are mostly behind us. Professional diagnostic equipment can cost thousands of pounds, and without it, you’re basically guessing at the problem.
Plus, getting it wrong can cause more damage and end up costing you more in the long run. Your car’s full service history can be affected if repairs aren’t properly documented, potentially reducing its value when you come to sell. DIY fixes for electronic issues like P0202 have only a 23% success rate, compared to 97% for professional repairs by qualified car specialists.
Before entering your vehicle details into random online diagnostic tools, consider bringing it to a professional service centre like ours. The process of fixing a P0202 fault code will vary depending on the specific issue, but we’ll always provide a clear quote upfront.
If you do want to try something yourself before booking a car service, the safest option is to disconnect your battery for 15 minutes (this can sometimes reset the computer) and then use a high-quality fuel system cleaner. But if the light comes back on, it’s definitely time to contact us for proper help!

Frequently Asked Questions About P0202 Fault Codes
Is it safe to drive with a P0202 fault code?
While your car will likely still run with a P0202 code, it’s not recommended to drive it for extended periods. You might damage other components like your catalytic converter, which is much more expensive to replace than fixing the original problem. Short journeys to get to the garage are usually fine, but don’t delay booking a car service.
How urgent is fixing a P0202 code?
Our car specialists recommend getting it checked within a week of the code appearing. It’s not usually an emergency (unlike brake problems, for example), but it shouldn’t be ignored for months either. When your car service due notification appears alongside this code, consider it a priority.
Will a P0202 code make me fail my MOT?
Yes, it potentially could. If the fault is causing your emissions to be too high, you’ll definitely fail the MOT testing emissions check. It’s better to get it fixed before your MOT is due. Our service centre can help ensure your car is MOT-ready.
Can bad fuel cause a P0202 code?
Yes, contaminated fuel can sometimes cause injector problems that trigger this code. If you’ve recently filled up at an unfamiliar petrol station and then got this code, fuel quality might be the issue. We might recommend an oil and filter change if the fuel has contaminated your engine oil.
How does the type of car affect P0202 repairs?
The type of car service required can vary depending on your vehicle manufacturer. European models often have different injector setups than Japanese or American cars, and premium brands typically have more complex systems that may require specialist attention.
How long does it take to fix a P0202 problem?
At First Auto Centre, diagnosing the problem usually takes about an hour. The repair time depends on what’s causing the issue, but most P0202 fixes can be completed within 2-3 hours as part of our vehicle servicing options.
How does regular servicing prevent P0202 problems?
Regular servicing following manufacturer-recommended servicing schedules helps catch potential injector issues before they trigger fault codes. Changing your oil and filter regularly prevents contamination of the fuel system, while full car service packages include injector cleaning and inspection.
How much do fuel injectors cost?
The price will vary depending on your car. For a basic Ford or Vauxhall, you might pay around £30-£70 per injector for a quality aftermarket part. For a BMW, Audi, or Mercedes, you could be looking at £100-£300 per injector or more for genuine parts. Our servicing pricing is always transparent, so you’ll know costs upfront.
Remember, for any questions about fault codes or to service your car, you can always contact us at First Auto Centre. Our car specialists are here to help keep your full service history up to date and your car running smoothly!
