Dirty Fuel Injectors

The first culprit behind the Nissan Qashqai injector problems is the dirt and grime accumulating on the injectors over time. This can happen due to bad fuel quality or incorrect maintenance practices by the vehicle owner.

You need to get your fuel injectors cleaned regularly to solve this issue. The best way to do this is to remove them from their casings and then send them off for professional cleaning.

Apart from that, you can also solve it yourself if you want to get your hands dirty. All you need to do is remove the car’s injector and clean it properly with an old toothbrush and a little cleaning agent. This will cost you around $50 if you do it alone.

Doing it yourself at home may seem attractive, but it isn’t recommended as it can cause more damage if done incorrectly.

Leaky Fuel Injectors

Another common problem experienced with Nissan Qashqai injector problems is leaking fuel from the injector into other parts of the engine bay. This could be because of a faulty O-ring seal or incorrect installation of the injector itself.

Fixing the leaky fuel injector depends on how bad the situation is. For example, as mentioned above, you can replace the O-ring seal if it is just a minor external leak.

However, if it is a major internal leak, then you may need to get your injectors professionally replaced. This is something other than what we recommend doing on your own, as it can cause severe engine damage if done incorrectly.

Faulty Fuel Pump Issues

In some cases, the Nissan Qashqai injector problems can be caused by a faulty fuel pump responsible for providing pressure to the injectors. This can lead to decreased performance and an overall increase in fuel consumption.

A faulty fuel pump can be identified with the help of several indicators. This includes the car consuming more fuel than the required amount or engine stalling or randomly.

To solve this problem, you need to replace the fuel pump with a new one from a reliable source. This should be done as soon as possible to prevent further issues.

Uncoded Injectors

In some cases, the Nissan Qashqai injector problems can be caused by uncoded injectors. This happens when the existing injectors’ codes do not match that of the car’s engine control unit.

If you experience this issue, you will receive the engine trouble code P0202, indicating a problem with the injector circuit. This may sound a bit nerdy to some people, especially if you are not tech-savvy, but you can still fix it with a little effort.

To solve this problem, you must get the injectors scanned and coded with a compatible scanner tool. This can quickly be done by any auto repair shop in your locality or a professional Nissan technician.

Apart from that, you should also take proper care of your car and ensure that the injectors are serviced regularly to prevent any problems.

Dead Fuel Injectors

Dead Fuel Injectors

Last but not least,  the Nissan Qashqai injector problems can also be caused by dead fuel injectors. This happens when the ECU cannot recognize or activate the existing injectors because of their faulty wiring or bad connections.

Dead fuel injectors cause the engine’s performance to decrease significantly, and it should be fixed as soon as possible. To fix this problem, you must send your injectors away for a professional diagnosis and repair.

Once the dead fuel injectors are fixed, you should also check the other engine components to ensure that everything is working correctly. This will help you maintain your car’s performance for a longer period of time.

To get your vehicle back on track and prevent further problems, you should take your car for a professional diagnosis as soon as possible. This should help determine the root cause of the problem and provide suitable repair solutions.
