Where to test engine compression on Honda Civic?
Testing the engine compression on your 1.6L Honda Civic (Civic del Sol) is a pretty easy and simple affair, since the spark plugs are right on top of the engine. This tutorial will walk you through the entire process in a step-by-step fashion and will also help you interpret your test results. Contents of this tutorial:
Why does my Honda Civic have low compression?
Typically if only one cylinder is low on compression, the motor will just run poorly. The causes for low cylinder compression are typically a bad head gasket, worn piston rings, or bent valves. Low compression from those problems are also accompanied by other problems, like coolant in the oil, an engine that burns oil, or noisy operation.
What causes low compression in Honda 1.6L engine?
Usually caused by very low compression in one cylinder or… Uneven engine compression that varies more than 15% across all 4 cylinders. A Cranks but Does Not Start condition .
Why does my Honda Civic not start up?
Honda’s D-series and B-series motors are both interference engines. If the timing belt broke while the car was driving at any point, there’s a real likelihood that the pistons have bent the valves. A compression tester is necessary in order to get the pressures inside each cylinder. Remove one spark plug and replace it with the compression tester.

How do you know if your Honda Civic has a spark problem?
Take the engine spark plug wires, and plug them onto the end of the spark plug one at a time. Have an assistant crank the engine, while you watch the plug for a spark. You should see white light arcing between the electrodes of the plug. Make note of any wires that fail to deliver a spark to the plug.
How do you fix a spark plug on a Honda Civic?
If the visual image of this is not clear, hold the spark plug at an angle from the grounding point (with the ground touching the threads of the spark plug), and the electrode free of any obstructions. Take the engine spark plug wires, and plug them onto the end of the spark plug one at a time.

What should I do if my Honda engine has no compression?
Now, if it turns out that one or several cylinders, on your Honda, do have low or no compression, the next step would be to do a ‘Wet’ engine compression test (and I’ll show how to do one too). The engine’s temperature is an important consideration before you start the engine compression test.
What happens when you stop the Honda Civic a / C compressor?
Discharge pressure abnormally high After stopping A/C compressor, pres- sure drops about 196 kPa (2.0 kgf/cm2, 28 psi) quickly, and then falls gradually. Air in system Recover, evacuate, and recharge with specifi ed amount. No bubbles in sight glass when A/C condenser is cooled by water.
Is there a compression test for a Honda Civic?
The engine compression test is one of the best ways to find out the internal health condition of your 1.5L Honda Civic’s engine. In this tutorial I’ll explain how to do a dry and wet engine compression test.
What causes low engine compression in Honda 1.5L?
Engine compression problems usually cause one of two things: a rough idle/misfire condition or a cranks but does not start condition. Having low or no engine compression in one cylinder on your 1.5L Honda will cause your engine to miss at idle and you’ll definitely feel there’s something wrong when you accelerate the vehicle.
Is there a problem with my Honda Civic?
This article explains how to diagnose and repair common misfire problems on your Honda Civic. This article applies to the Honda Civic (1992-2000). Your engine needs the perfect balance of fuel, spark, and air to run smoothly.
What happens when there is no compression on 2 cylinders?
When you have a situation where you have no compression on 2 or ALL 4 cylinders, you’ll see: The engine cranks very fast and this fast cranking speed is very noticeable. The ignition system is sparking all 4 spark plugs, so you know it’s not an ignition system problem/issue. The fuel injectors spray fuel.
How to test engine compression ( Honda 1.6L )?
Repeat steps 5 thru’ 8 on the other 3 cylinders. CASE 1: Low or no compression in 2 or all 4 cylinders. This test result indicates a serious internal problem. The most common issues would be: Blown head gasket. For further testing, go to: How To Test For A Blown Head Gasket (Honda 1.6L).
Why does my Honda engine not start when compression is low?
The next common scenario is having low or no engine compression on two ADJACENT engine cylinders and your Honda won’t start. It’ll Crank but Not Start. This usually indicates that the head gasket has burned between the two cylinders.
What happens when there is no compression on all 4 cylinders?
When you have a situation where you have no compression on ALL 4 cylinders, you’ll see: The engine cranks very fast and this fast cranking speed is very noticeable. The Ignition System is sparking all 4 spark plugs, so you know it’s not an ignition system problem/issue. The fuel injectors spray fuel. You can confirm this with a Noid Light test.
What is the diagnostic code for Honda engine compression?
When this happens (low or no compression on just one cylinder) and your Honda vehicle is OBD II equipped (1996+), you’ll see one of the following misfire diagnostic trouble codes: P0300: Random Cylinder Misfire. P0301: Cylinder #1 Misfire. P0302: Cylinder #2 Misfire. P0303: Cylinder #3 Misfire. P0304: Cylinder #4 Misfire.
Is the Honda Civic EX air conditioner working?
I have 2008 Honda Civic EX which now has 115,000 miles. The AC has been working intermittently for the past year and half. I checked the low side pressure and was right where it should be. Finally, wife couldn’t take it no more.
Can you add Freon to a Honda Civic?
The A/C system in your Civic consists of a compressor that is belt-driven, an evaporator and freon. If there is a problem with your compressor or evaporator, adding freon will not restore cooling. How to add freon to your 2008 Honda Civic: hook up the can of refrigerant (likely r-134a) to the low pressure port.
