The Check Engine light of my Nissan 2000 turned on while I was driving home from work. I had to pull on the shoulder to check the engine, but nothing looks different. What's wrong with my vehicle?
There can be several reasons behind an illuminated Check Engine light, but one of the most common is a failed ignition coil. When this happens, the coil causes the spark energy to send a feedback through the wiring harness into the other coils. It is important that you replace the worn-out coil to keep the other coils from being damaged as well. Another reason for your Check Engine light to turn on is a failed catalytic converter. When the cat-con closest to the cylinder head wears out, it will cause this light to illuminate. Repair or replacement of the cat-con is necessary to avoid the catalyst material to be sucked into the engine, which can cause internal damage.
Recently, I noticed that there is a knocking sound whenever I drive over bumps on the road. I've also been experiencing problems controlling my vehicle. What could be the problem with my Nissan 2000?
If you can hear a knocking sound whenever you drive on rough terrain, then it is probable that the power steering pump of your vehicle might be leaking. This part is responsible for regulating the flow of hydraulic fluid into the sealed system of hoses. When this pump wears out, it can cause leaks that can drip onto the lower control arm bushing. Failure to fix this leak can cause the bushing to deteriorate and create the noise. It is essential that you fix this immediately to avoid having steering problems.
I was driving my vehicle one evening when the engine stalled on me. It has happened for three times already, and I wonder if something's wrong with my engine. What should I do?
Engine stalling is not an unusual problem especially to Nissan vehicles. The engine is prone to stall at times when your crankshaft position sensor and/or your camshaft position sensor have already worn out. These sensors play an important part in your vehicle, and when they fail, they can result in engine stalling. Sensors on certain models have already been recalled by the manufacturer. You may want to check with your dealer if your unit is included in the recall. If not, it is important to have these sensors replaced immediately to avoid further damaging your engine.
Lately, I've been experiencing issues when driving my 2000. My trusted technician said that the mass air flow sensor has failed. What are the repercussions of this problem, if left neglected?
The mass air flow (MAF) sensor of your vehicle is important to be able to find out the mass flow rate of air entering your engine. This information is necessary to deliver the correct fuel mass to the engine. When this part fails, you might experience high fuel consumption, starting problems, and driveability issues. It is important to have your vehicle checked and diagnosed by an expert immediately.
