What do u understand by hard starting of the engine

When a hot engine is hard to start, most of the causes are fuel related problems. Fuel cannot circulate well due to the way in which vapor blocks it. As a result, the engine would not start as easily as it should. In worse cases, it would not start at all. This happens if the engine is extremely hot.

Until after a while the engine was shut off, it would keep on acquiring temperature. The biggest amount of water vapor would be spreading around during this process. It therefore means that during this period, there are higher chances of its obstruction to the engine. So when you are driving in hot weather and you have just turned off the car and you experience difficulty in stating the engine, do not panic. Just wait for a couple of minutes and then start it back.

Because the fuel remains inside the injectors by being under a very intense pressure, engines that are fuel injected do not experience and suffer this problem as much as others do. In this case, fuel injected engines would not become so easily moved by vapors as compared to other engines. From this fact, it can be further deduced that auto mobiles may have different problems in starting their engines.

A cold start is an attempt to start a vehicle's engine when it is cold, relative to its normal operating temperature, often due to normal cold weather. A cold start situation is commonplace, as weather conditions in most climates will naturally be at a lower temperature than the typical operating temperature of an engine. Occasionally, the term also refers to starting the engine of a vehicle that has been inactive or abandoned for a significant amount of time such as months, years or even decades.

If the check engine light comes on: Look for a serious problem that requires immediate attention. Check your dashboard gauges and lights for indications of low oil pressure or overheating. These conditions mean you should pull over and shut off the engine as soon as you can find a safe place to do so.

It's a scenario that's befallen drivers everywhere: They turn on the car and start to fiddle with the radio and the air. They glance left and right over their shoulders while buckling up to check whether they're clear to back up. They put the car in gear, ease it down the driveway and go on their way. Then suddenly they glance down at the dash and notice with horror -- the check engine light is still on!

What does this mean? Well, for starters probably a pretty annoying day. If your check engine light is illuminated, it's best to take it in for diagnostic testing, which can feel like a hassle. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There's a problem with the car's emissions system. The on-board diagnostics system and engine control unit are in charge of monitoring a bunch of different parameters, and if they get a reading that's a little out of whack, up pops the check engine light

There are tons of toyota threads in this section. Don't boycott them because you wanna run Business PR.

You cant just be doing copy and paste up and down na

"ease down the drive way"..."up pops the Check engine light ".....who uses all these terms in naija?

Write stuffs in ur own words,or give credit to the source u copied from

That cant be hard

Bros I recently changed my ABS of sienna 2000 model when the speedometer did'nt work.. but since the change of the abs my sienna started consuming fuel and doing black smoke.... i hav been doing try.and error since this new issue ... but my new mechanic said the car BrainBox need to be change again.... i want help will fault brain box cause this?

Uncle Marpol pls shut this thread down. I

there is no relationship whatsoever between change of abs which is a chassis system device with your car fuel management system which is your powertrain .
It might just be a coincidence ,if you are in Lagos ,call autologic @ 08061166316 to run a comprehensive diagnosis on your powertrain system

If the amber ABS warning light comes when you apply the brakes, or if the ABS warning light remains on all the time, your ABS system has a fault and has disabled itself. This means your ABS system cannot intervene if you need it during a hard panic stop or when braking on a slick road.

The Check Engine Light (which is actually the Malfunction Indicator Lamp or MIL) alerts you when an emissions-related problem occurs with the engine control system or emission controls on your vehicle. Depending on the nature of the problem, the Check Engine Light may come on and remain on continuously or flash. Some intermittent problems will make the Check Engine Light come on only while the fault is occurring (such as engine misfire). The Check Engine light usually remains on once a fault has been detected, and will remain on to remind you that a problem has occurred that needs to be investigated.

An illuminated Check Engine Light can be annoying because you don't know what's wrong, and whether or not the problem might be a serious one or just a minor fault. There is no way to know what the problem is until you plug a scan tool into the vehicle's diagnostic connector and read out the code(s) that turned the light on.

If no other warning lights are on, and the engine seems to be running normally (no unusual noises, smells, vibrations, etc.), you can assume the fault that is causing the Check Engine Light to come on is probably minor and won't hinder your ability to continue driving. But if other warning lights are on, you should probably stop and investigate the problem.

When the Check Engine Light comes on, a diagnostic trouble code (DTC) is recorded in the powertrain control module (PCM) memory that corresponds to the fault. Some problems can generate more than one trouble code, and some vehicles may have multiple problems that set multiple trouble codes.

CHECK ENGINE LIGHT ON SETS TROUBLE CODES
In most older vehicles (those made before 1996), disconnecting the computer's power source or disconnecting a battery cable erases fault codes and turns off the Check Engine Light, at least temporarily. If the problem persists, the code will reset and the Check Engine Light will come back on. But on many newer vehicles, you do NOT want to disconnect the battery because doing so can wipe out the computer's memory settings. This may affect the operation of the transmission, climate control system and other functions.

In 1996 and newer vehicles, a scan tool or code reader must be used to erase codes and turn the Check Engine Light off.

Oxygen sensors monitor the amount of oxygen in the exhaust so the engine computer (PCM) can adjust the fuel mixture to minimize emissions and maximize fuel economy. There are two types of oxygen sensor trouble codes: O2 heater circuit codes and O2 sensor codes. A heater codes will set if a fault is detected in the circuit that warms up the oxygen sensor when your engine is first started. This is necessary to reduce cold start emissions. An O2 sensor performance code will be set if the O2 sensor readings remain low (lean), or high (rich), or do not change quickly enough, or do not change at all.

The thermostat speeds engine warm up after a cold start, and regulates the engine's operating temperature when it is running. If the thermostat sticks shut, it can cause the engine to overheat. If the thermostat fails to close, the engine may never achieve normal operating temperature. This will prevent it from going into closed loop feedback control of the fuel mixture (which makes the engine run rich and waste fuel).

I need help my Corolla 011 transmission slips when I kick down the

It accelerate well when I gradually accelerate or use cruise control to increase speed the revs upwards but does not increase speed I have changed the transmission oil

No hard shifting is observed no sound

But der is delay in shifting from 2-3 it moves to 2 easily
