Symptoms of a Bad or Faulty PCV Valve Hose
Common symptoms include poor fuel economy, Check Engine light coming on, engine misfiring at idle, and engine noise.
The positive crankcase ventilation (PCV) valve hose carries excess gases from the crankcase to the PCV valve. From there it is added to the intake manifold and used by the engine. If the PCV valve hose breaks, gas will not flow back to the engine and your vehicle will be less efficient and have higher emissions. There are a few symptoms to look out for if you have a bad or faulty PCV valve hose.
1. Poor fuel economy
If the PCV valve hose is clogged or leaking, this can result in poor fuel economy. This is because the vacuum on the intake side of the cylinder head will not be able to correctly signal the correct amount of fuel to be delivered to the engine and can cause the engine to be lean or rich. If you suspect that the PCV valve hose is causing poor fuel economy, contact AvtoTachki to replace the PCV valve hose.
2. Check Engine light comes on.
The Check Engine light can come on for a variety of reasons, and one of them is a PCV valve hose malfunction. This is because the PCV valve hose works directly with your engine to ensure everything is working properly. AvtoTachki mechanics can diagnose the exact cause of the Check Engine light, whether it's a PCV valve hose, a PCV valve, or a combination of parts.
3. Misfires at idle
Another sign of a bad or faulty PCV valve hose is your vehicle's misfire at idle. This may be due to loss of vacuum due to hose malfunction due to leakage, hose pinching, or clogging due to buildup of deposits over time. Misfires will sound like the engine is vibrating, which is a sign that it is not working properly.
4. Engine noise
If you hear a hissing sound from the engine, it's time to check your car. The PCV valve hose may be leaking, causing a hissing sound. Leaving it on for too long can cause misfires, rough running, vacuum leaks, and you'll have to do more extensive repairs.
