Engine Pinging Noise While Driving

Engine Pinging Noise While Driving

When the car makes pinging noise while driving, the noise usually indicates a problem related to the engine. However, there are other causes like the use of cheap low octane gasoline or may also cause by driving the car in high altitude areas.

Reasons why engine makes pinging noise while driving

(1) Use of low octane gasoline
(2) Driving at high altitude area
(3) Engine related problem

Use of low octane gasoline
Low grade or "cheap" gas is generally considered to be gas with an octane rating of 88 or below. The bad thing about low-grade gas is that it burns too easily. Put another way, low-grade gas is too combustible. You see, the gas that burns too easily will, under certain conditions, self-ignite before the piston reaches the top of the combustion chamber... this is known as pre-ignition. When pre-ignition occurs, you'll hear a pinging sound.

Engine Pinging Noise While Driving

Generally, pre-ignition only occurs under conditions such as when the engine is under stress and/or really hot. When driving up a hill, the engine is under stress. This stress will trigger pre-ignition (and thus pinging).

What to do?
Use higher octane gasoline. High octane fuels have a rating of 92 or above and are usually called "Super" gasoline. Incidentally, the octane rating is displayed on the front of the gas pump.



Driving at high altitude area
If the only time the engine makes a pinging sound is on high altitude roads. What is significant about high altitude roads is the fact that the air is thin. Now, when an engine is both under stress (e.g. driving up a hill) and it has only thin air for combustion, the fuel will tend to ignite in the combustion chambers before it is should. This condition is known as "pre-ignition". When pre-ignition occurs, a pinging sound results.

What to do?
Try using high octane gasoline the next time you anticipate driving on high altitude roads. High octane fuels burn slower and are therefore more resistant to pre-ignition. If pre-ignition is eliminated, pinging is eliminated as well. High octane fuels have a rating of 92 or above and are called "Super" gasoline. By the way, the octane rating is easy to determine... it's displayed on the front of any gas pump.

Engine related problem
If the car has fuel injection. Fuel-injected engines have a gadget called a "load sensor". The purpose of this sensor is to measure the load/stress on the engine. When the load is high, such as when driving up a hill, the load sensor (if working) will send a signal to the engine's control unit to indicate a "high load" condition. Based on this signal, the control unit makes a calculation and uses the result to adjust the engine's operation so as to avoid pinging. Clearly then, if the load sensor isn't working, the engine will probably ping when driving up a hill. From the above, you may be thinking that the control unit could be faulty and not the load sensor.  Although this is possible, it's rare.  Further, if the control unit was faulty, the engine would probably not run at all.

What to do?
Take the car to a car repair shop and have the mechanic check the load sensor.  If it is indeed faulty, have it replaced. When talking to the mechanic, try to describe the nature of this problem just as described in this article. Don't ignore this pinging sound.  Pinging is actually an indication of something called pre-ignition.  When left uncorrected, pinging/pre-ignition can ruin an engine. If you aren't currently using "Super" gas, try a tank. Super gas is formulated to resist pinging and thus can act as a temporary fix to this problem.

Honda Civic Won’t Start Makes Clicking Noise

Honda Civic Won’t Start

Honda Civic Won't Start

Does your Honda Civic won’t start, makes clicking noise during starting? Since the engine is not starting there are two possible reasons why your Honda civic is not starting, clicking noise that is heard during starting is because of the solenoid from the stater. The solenoid is the one that allows the current from the battery to flow into the starter to make the engine crank. With that said the possible cause of the problem is a weak battery or the starter is failing.

How to Jump Start a Car Battery
Jump starting a car is easy but should be done correctly so that accidents such as a battery explosion can be avoided.

Now, before going into the starter, the first part to check, and the easiest one, is the battery.

Here's what you do:

1) Turn the ignition "ON" to the position before the clicking sound is heard, this is the position when the ignition key is turned before turning it again to start the engine.

2) Turn the windshield wiper on and leave it in operation for about 30 seconds. Windshield wiper runs off the battery when the engine is running. Observe the wiper while it runs, if the windshield wiper runs slower than it's normal operation, then there is a problem with the battery or the battery may be weak.




3) Open the hood then locate the battery. Remove the battery terminal, see how to disconnect the battery terminal, then observe the battery terminals ant the battery pole. Check the battery terminals for any corrosion. If you observed that there is a presence of cruddy like substance on the terminals then it means that the terminal is corroded or there is corrosion on the battery terminals. The corrosion is preventing or restricting the current to flow from the battery into the starter. If the starter does not receive enough amount of current to start it, likewise the starter will not start your honda civic.

How to Check Battery Cables



However, if the battery is in good condition then the problem is the starter. There are two possible reasons why the starter won’t work, either a bad electrical connection or a bad starter. Both will cause the starting problem in the car. To diagnose the problem first is to check the starter electrical connections, locate the starter and check the wire if it is secure and tight. If the wiring is OK then the problem is the starter. Replace the starter.

How to fix if your honda civic won't start and makes clicking noise?

Remove the corrosion in the battery terminals. Clean the terminals using a wire brush, apply two spoonful of baking soda mix with two spoonful of water to the terminals, wait for a few minutes to dissolve the corrosion before brushing the terminals then wipe the terminals with a clean cloth, after removing the corrosion apply petroleum jelly on the terminal to prevent corrosion deposits on the terminals in the future.

Temperature Gauge Reads Hot During Traffic

Temperature Gauge Reads Hot During Traffic

When temperature gauge reads hot during traffic it means that there is something wrong with the fan. This particular problem suggests that there is something wrong with the fan. You see the main purpose of the fan is to keep the engine cool when the vehicle either moving slowly or stop such as in prolonged slow traffic.
