Why is the radiator fan not working on my pulsar?

If the engine coolant level isn’t high enough to keep pressure in the engine it will run hot. But, there won’t be enough coolant to reach the temperature sensor. Without the coolant hitting the sensor, the temp reading will be significantly lower than the actual engine temp. Your Pulsar’s radiator fan will not kick on.

What are the symptoms of a bad MAF sensor?

Here are the most common symptoms of a bad or failing MAF sensor: Idle Issues – Your Patrol may run rich or lean when idling, or it may also idle erratically. A rich condition is when there is not enough air relative to the fuel in the air/fuel mixture. The exhaust color is usually darker when running rich.

The symptoms of a bad mass air flow sensor include low engine power, poor fuel economy, an engine that won’t start, a check engine light on the dash and a gas smell from the exhaust fumes. A bad mass air flow sensor is often the likely culprit if your car isn’t running as it should.

How does an air temperature sensor work in a car?

The energy required to maintain the sensor at the same temperature is calculated and sent to the powertrain control module (PCM). The PCM then controls the injectors to deliver the specific amount of fuel that’s proportional to the airflow, creating an air fuel mixture that, ideally, is perfect for your engine. Vehicle-specific.

Why does my Nissan Maxima engine not start?

There are a lot of issues that can cause your Maxima to crank, but not start. The engine needs air, fuel, and a spark in order to run. It is highly likely that if the engine is cranking, but not starting that it has thrown an OBDII code. It is definitely worth it to use an OBDII scanner to check and see if the engine has thrown any trouble codes.

The symptoms of a bad mass air flow sensor include a car that is difficult to start, bad fuel economy, a rough idle, lack of power especially when accelerating and sometimes a fuel smell from the exhaust fumes. A properly functioning MAF sensor is vital for an engine to run efficiently.

Why is my Nissan mass air flow sensor not working?

by Dan Ferrell. The mass airflow sensor (MAF) in your Nissan vehicle measures the amount of air going into the engine. If the MAF sensor sends the wrong signal to your car’s computer–because of dirt or other contamination around its sensing elements–your engine will be fed with the wrong amount of air/fuel mixture.

What can a Nissan Quest mass air flow sensor do?

A defective Nissan Quest mass airflow sensor could make your car difficult to start. Your ECU uses the mass airflow sensor input to determine the fuel ratio that the injectors need to deliver to the engine. If your check engine light is still on, use an OBD2 scanner to clear any stored codes in the ECU.
