How to troubleshoot a Honda Civic temperature gauge?
A malfunction on the gauge is simple to troubleshoot. With this guide, you will be able to locate the fault and make the necessary repairs in a matter of minutes. Turn the ignition switch to the On position but do not start the engine.
What do you do when your Honda engine is at idle?
An easy way to find one of these faulty PCV valves is to pinch off the supply line to the PCV valve with a pair of pliers while the engine is at idle. If the idle smoothes out when you do this, replace the PCV valve with an OE unit.
How does the fuel system work in a Honda Civic?
The fuel system in your Honda Accord and Civic consists of many working parts. Each part is designed to work in sync with your car’s entire fuel system to deliver optimum fuel flow to the engine, and sustain the normal operation of your vehicle’s idling, acceleration, and speed.
Why is my Honda Civic not turning on?
If the fan isn’t kicking in, then there a few things that could cause that. One of the reasons could be a faulty thermostat, as the thermostat tells the fan when to turn on and off. Another reason could be that the fan’s wiring harness is not getting power to actually turn the fan on.
Why is my Honda Civic having Idle problems?
Continue reading to find out what can cause your Civic to have idling problems. A car with a vacuum leak can cause an unstable idle. An unplugged vacuum line (as well as a damaged air intake hose) creates discrepancy between how much air the engine’s computer thinks it has, and how much it actually has.
Why does my Honda Civic speedometer keep going up and down?
When a speedometer malfunctions, it may function in many different ways, including constant idling, rising when the car is idle, reporting an incorrect speed, and bobbing up and down. When a Civic’s speedometer malfunctions, it could be caused by a number of problems.
What does hunting idle mean on a Honda?
The computer also fights them as it tries to maintain an idle using the IAC but it can’t keep up so you get a ‘hunting’ idle condition meaning that the idle fluctuates from high to low and it never levels out. This condition is often worse after the engine warms up.
Can a Honda EGR cause it to idle?
EGR will not effect idle unless it’s stuck open. Many people go here but to be honest it’s hardly ever the cause of an idle problem on a Honda. When the EGR is a problem it often causes a miss under load NOT an idle issue.
What should I do if my Honda Civic won’t start?
The check engine light will likely appear if your car won’t start. If the engine won’t turn over, or if there’s no sound from the starter when turning the key, the battery is likely dead. The easy way to test the car battery is with a multimeter. Connect the multimeter to the positive and negative battery terminials.
What does check engine light mean on Honda Civic?
If the car won’t start, the “check engine light” is almost certainly on. This light means the engine computer has codes stored that identify a malfunction. The first step to figuring out what’s wrong is to pull those codes. Civics built before 2006 can display the codes on the gauge cluster through a series of flashing lights.
How can I tell if my Honda Civic is working?
Civics built before 2006 can display the codes on the gauge cluster through a series of flashing lights. Later model Civics will need to pull codes through an OBD2 scanner. These codes will give a good starting point towards figuring out what exactly is malfunctioning.

Where to find OBD I code on Honda Civic?
Honda Motor Corporation OBD I diagnostic trouble codes are retrieveable without any special tools by simply following the instructions here. The codes are listed for Accord or Civic models seperately when required. The codes are defined as to what system is affected. When possible we give the more commonly known OBD II component name.
What causes an engine temperature gauge to stay on cold?
Reasons Why your Engine Temperature Gauge Stays on Cold 1. Faulty Engine Coolant Temperature Sensor 2. Faulty Gauge/Cluster 3. Broken wires to the sensor or to the gauge 4. Bad Thermostat 5. Corrosion in connectors 6. Air in the coolant system 7. Broken engine control unit
How many temperature sensors does a car have?
Some cars have two temperature sensors, while other car models have one. The models with one sensor usually both use the engine control unit’s temperature and the same sensor for the gauge. If your car model has two coolant temperature sensors, one is used by the temperature gauge, and one is used for the engine control unit.
Why is my car temp reading so high?
Another reason your reading might be high is you could be losing coolant. A small leak or evaporation may cause your radiator to slowly lose coolant. A third reason your temperature gauge reads high could be because the thermostat is broken. If this is the case, you may need a coolant temperature switch replacement.
What’s the temperature gauge on my Honda CRV doing?
I have this recurrent problem with my 2002 Honda CRV. Last year my temperature gauge started acting up. It would remain at 1/2 mark after warming up but while driving it would sometimes go all the way to 0 and then come back up till 1/2 mark.
How to know the temperature of your car?
Start off and head toward a highway. Have the heat on HI, with the fan just enough ON so you can feel it. Then watch your gauge and air temp as the car warms up. the air should get warm in just a minute, before the gauge starts to rise.
Why does my Mazda car have no temp gauge?
According to Robert Davis, Mazda’s senior vice president for quality, research and development, there’s a cool blue ‘cold’ light instead of a temperature gauge because of consumer psychology: In short, owners are more likely to drive gently—and “not thrash the engine”—if there’s a light on than if the temp gauge simply shows cold.
What does intermittent mean on car temperature gauge?
The code indicates that a wire from the engine coolant temperature sensor, is shorting to ground, or open, somewhere. Of course, “intermittent” means: sometimes. The engine computer, in response, turns on the engine cooling fans, to lower the reported hot engine coolant temperature.
