Question about 1999 Kia Sephia

1 Answer

Wrong readings of speed gauge

Speed indicator readings don't make a sense. They are low sometime. the reading nearly equals half or the real value -that was determined by comparison between rpm and speed. Almost after exceeding 40 km/Hr at the gauge, the reading jumps to double value and it becomes logic reading.
I want to know where the problem is and how can i solve it.
thank you

The speedometer is electronic and more than likely in need of repiar. 2 choices here; get it rebuilt, or replaced. call a salvage yard in your area and see if they have one. the problem lies in the gears inside the unit and are sealed. you can do more damage trying to fix it if you re not familiar with speedomemters.

What are the specific ac temperature gauge readings on 2011 buick across?


The low side reading will usually correspond with the dash temp,45 lbs at low side should equal 45 degrees f at the dash with a medium fan speed and 70 to 80 degrees f outside temp with a good air flow through the condenser.(fan placed in front of vehicle).

My car 2008 Chevy Uplander warning light came on stating A/C shut off for engine protection. My question exactly as 1posted 2011. Gauge not Reading. Fan running continuously. Doesn't seem hot.


What gauge not reading , Temperature ? you posted back in 2011 ? You did feel you should take it to the repair shop ? You need to take this to a ASE certified repair facility ! This is a complex electronically controlled cooling system , Three relay's controlled by the ECM -engine control module turn the fans on in two different speeds ! There could be DTC'S diagnostic trouble codes stored in the ECM, HVAC module , BCM !
Circuit/System Description
The engine control module (ECM) commands the fans ON in high speed or low speed. In low speed, the fans are configured in series. In high speed, the fans are configured in parallel.
In low speed operation, the ECM applies ground to the coil side of the low speed fan relay, which is the Fan 1 Relay. Voltage is applied directly to the left cooling fan through the switch side of the low speed fan relay. The right fan is connected in series to the left fan through the de-energized Series/Parallel relay, which is Fan 2 Relay, so that both fans operate at low speed.
In high speed operation, the ECM applies a ground to the coil side of the low speed fan relay, the Series/Parallel relay, and the high speed fan relay, which is the Fan 3 Relay. Voltage is applied directly to the right cooling fan through the switch side of the high speed fan relay. The left cooling fan obtains voltage through the low speed fan relay and ground through the Series/Parallel relay.
When the ECM is commanding a fan relay ON, the voltage of the control circuit should be low, near 0 volts. When the ECM is commanding a fan relay OFF, the voltage of the control circuit should be high, near battery voltage.
One of the relays could be stuck on ! An for the gauge you have to have it removed an fixed , there is a stepper motor behind the gauge needle an they go bad ! Or replace the instrument cluster !

Engine light and low temp on 96 cavalier


the engine light is telling you something has gone wrong and you should stop and check it out. The low speed indicates that the CPU is in low power mode to protect the engine. The low temp reading is suggesting no coolant in the engine. Check oil and coolant level and have a fault code reading done before you cause more damage to the power train

Warings lights coming on, SLIP indicator,CHECK indicator, VSC OFF indicator,comes on.


Sounds like a wheel speed sensor may be out of range as far as expected values compared to other wheel speed readings and the VSC goes off because it cannot work with unexpected data values coming into the VSC module. There may be a false high speed reading on one or more of the wheels.

Oil pressure guage drops low when at idle but when excelerating reads normal kmello@sousademayo.com


Mine does the same thing, the gauge is like a tachometer, it revs like crazy, but holds steady at high speed, it goes down to about 10 at idle, 35 at cruise speed and it will go up to 55 if I step on it. But remember it is just a pressure gauge, it will read this pressure with 1 qt of oil in there, so don't use it for a level indicator. Check the oil, and you know if it has oil in it. Hope this helps.

I have full gas in my car but still no cold air inside the car


If you over charged the system your a/c will not work. To diagnose problems, an A/C manifold gauge set is needed to read high and low side pressure readings. Avoid adding refrigerant with a simple charging kit like the ones sold at parts stores. Don’t add any stop leak, this can cause problems in the compressor, expansion valve or condenser.
Keep in mind that using an A/C gauge set and seeing BOTH high and low side readings can help in diagnosing the problem when you know what to look for. First, on a 134A system the high and low side service ports are different sizes. AC gauge sets have color coded hoses, the blue color coded hose has a connection that fits on the low side service port and the red hose has a connection that will only fit onto the high side. The yellow hose won’t hook up to anything if just checking the readings; it can be used to connect to a vacuum pump or attached to a refrigerant can or tank.

Normal readings on high and low side with AC OFF (static pressure) - Depends on outside temperature, but normally is between 80-105PSI  Normal low side reading with AC on high speed and MAX & engine at 800-1000 RPM’s - Ranges from 25-35 PSI - Note that on many Chrysler products a normal reading on the low side may be 15-25PSI  Normal high side reading ranges from 200-350 PSI
Don’t assume that if adding little Freon is good that adding a lot is better!  Overcharging just a little can decrease the performance of the system and possibly damage the compressor.

With the AC on the coldest setting, use a thermometer in a middle vent. Normal vent temperature readings will vary depending on the (ambient) outside temp. The vent temperature should range from around 42-55 degrees in my experience. If normal gauge readings are obtained and the vent air is cold - STOP don’t overcharge the system. The only proper way to remove refrigerant is with a AC recovery machine so if this is being done at home I can’t emphasize enough not to over charge the system. And actually the best way to insure the proper charge is in a system, is to use an AC machine to recover the freon and then evacuate and recharge the system with the correct amount. Most cars have the specified amount on a decal under the hood. 

Both low and high side readings are lower than normal, this indicates a cars AC system is low on refrigerant and is under-charged.

If both low and high side readings are too high, this indicates an overcharged system - too much refrigerant. This also can indicate that the condenser fan is not working, is too slow or the car is overheating and heat is transferring from the radiator to the condenser.

Good luck and hope this helps, keep me posted be glad to answer any question you may have.

it sounds like you are getting a surge of voltage from your alternator/generator. Very strange.

the dealer can run a diagnostic test & pull fault codes or you can try this. If this helps, please report back & rate as fixya. Thanks. I am curious what you find as root cause. Good luck.

Instrument Cluster Self-Diagnostic Mode
To enter the instrument cluster self diagnostic mode with the engine off, depress and hold the odometer reset button. Turn the ignition switch to the RUN position and hold until the gauges sweep (within five to eight seconds). Depress the reset button once to advance to each stage of the self-test.
Turn the ignition to the OFF position to exit the instrument cluster self-diagnostic mode. If no DTCs related to the concern are retrieved, proceed to the Symptom Chart to continue diagnostics.


Instrument Cluster Self-Diagnostic Mode Odometer display Description GAGE Carries out gauge sweep of all gauges, then displays the present gauge values. Also carries out the check sum test on ROM and EEPROM. All segments illuminated.
