This throws off the air-fuel ratio, resulting in rough idle , reduced fuel economy (often accompanied by the check engine light), and difficulty starting your vehicle. An active check engine light : The ECU monitors the amount of released fuel vapor and triggers the check engine light if it’s deficient or excessive.

The loss of fuel vapor also affects your car’s fuel efficiency , resulting in reduced mileage and increased emissions. This could cause your vehicle to fail an emissions test and damage your catalytic converter , resulting in costly repairs and hefty fines. But how do you identify an EVAP leak? Let’s find out.

An Illuminated Check Engine Light It’s almost impossible to physically detect an EVAP leak. So when the leak detection pump in the exhaust system suspects a small EVAP leak event, it immediately turns the Check Engine Light on. You may also notice a fuel smell from the engine due to the leaking gas vapors.

Active Check Engine Light Even though the check engine light doesn’t directly mean that your crankshaft position sensor is faulty, it indicates something is amiss. A crankshaft sensor detects the position and speed of your engine’s crankshaft. How Can I Prevent Crankshaft Sensor Malfunctions?

Blinking or Illuminated Check Engine Light A continuously illuminated or flashing Check Engine Light (CEL) is an early indicator of a failed oxygen sensor. However, the Check Engine Light can signal other problems, too. When this occurs, your vehicle is likely to fail the emissions test.

If the camshaft position sensor in your car malfunctions, it can disrupt the vehicle’s fuel injection and ignition timing by sending inaccurate or delayed signals to the Engine Control Unit (ECU). Note: The check engine light can also illuminate due to a bad crankshaft position sensor or other faulty components.

Check for these bad O2 sensor symptoms. Lit check engine light (CEL): A faulty O2 sensor is one of the most common reasons behind an illuminated CEL. This lit warning light may be because the bad sensor (upstream sensor) relays inaccurate readings to the Powertrain Control Module or shows a low oxygen level.

Starting Issues Since a failing fuel pump won’t send enough fuel to the engine, you’ll face difficulties starting your car. Lit Check Engine Light A bad pump will cause an air-fuel mixture imbalance, which will trigger the Check Engine Light. But how can you confirm fuel pump failure? Let’s find out.

Some misfire complaints are a flashing check engine light, and a P0300 to P0312 diagnostic trouble code (DTC) indicates that one or more cylinders are misfiring. Unfortunately, a misfire also will cause a considerable increase in hydrocarbon (HC) emissions, which can cause a vehicle to fail an emissions test.

This imbalance hinders the engine’s ability to achieve proper combustion, making it challenging to start the car. Failed Emissions Test Incomplete combustion can result in higher levels of unburned hydrocarbons and carbon monoxide in the exhaust. These increased pollutants can lead to a failed emissions test.
