Problem with engine rev. when turning the aircon

Usually to a vehicle, when you turn on your air conditioning unit. the rpm usually goes up a notch or so. in my case, my rpm gauge goes down, as if power given by my engine is not supplied properly or so... most of the time, when i drive a few hours, my engine tends to have a higher temperature than most vehicles driven with the same distance and time, also, when i park or stop on traffic jam, with my air-conditioning unit still on, my engine usually stalls due to lack of power or so... i own a 2000 model suzuki jlx model. hopefully somebody understands my question and helps me out with this one. thanks a million.

Hi,

In most cases, when the A/C compressor is activated, there is likewise a solenoid that is activated. This solenoid is mechanically couple to the throttle and basically increases the idling RPM . This is to compensate for the additional load that the A/C compressor puts on the engine. If this solenoid is defective or the connector detached, then it will not compensate when compressor is active. Then your idle goes down and the probability of a stall increases.

Slight increase in temperature as compared to other vehicles maybe due to:
1. improper mix of water and coolant;
2. defective or delayed opening thermostat;
3. clogged radiator tubing;
4. leak in the engine cooling system;
5. engine using higher octane fuel or improper oil;
5. engine in need of a major tune-up.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

    Gentlemen,

    It would appear that this "Inappropriate" rating is another malicious attack by an unscrupulous individual either to discredit me or lower my ranking.

    Your continued support in their removal would be highly appreciated.

    Hi again,

    No prob and its just a challenge to maintain a rank/rating.

    Back to your concern, I am under the impression that said solenoid is already existing and installed in your Suzuki. Perhaps what is needed is to simply adjust it to push the throttle a little bit more to increase the idling RPM. The solenoid would have an adjustable plunger and a lock nut. I'm guessing that it would require a 6-8mm wrench to adjust. Doing so would increase/decrease the idle. The lock nut would simply hold it in place. You may want to reference this page or this image.

    BTW, I am too in the Philippines.

    Cheers.

I have a 2004 lancer Es when I turn the aircon on after 15 minutes of driving I cant change the gears the aircon works fine but renders the gears useless and have to turn it off to continue to drive


There is no relationship between the air conditioning system and the gear box in the vehicle.

The engine operates the aircon compressor via the serpentine belt from the crankshaft pulley and if the aircon is operating normally the aircom compressor will not be faulty either.

If you are having problems with the gearbox it has nothing to do with the aircon system. The issue will be with the gearbox itself.

the engine doesn't like the extra stress of the air con unit being run _ there is no way of fixing this _ unless you get a full engine overhaul or a secondhand engine and installed _ the engine is old and the extra pressure on it with the aircon it just cant handle it

High idle benz 190e


Could be a defect in the ECU. But 1000rpm is not that high my cars normal is 1000rpm. but some older models were about 700rpm
The AC rise is normal. You may want to have a OBD II check by your garage or you can buy a unit to do this. It will scan the sensors fitted for any problems.

Why the rpm of toyota corolla 1994 model goes down when aircon is turned on


Because aircon uses a lot of power, it causes the revs to drop and the car to use more fuel. Just a fact of life. If you don't NEED to use the aircon - don't use it. And if you do need to use it, expect expenses to rise.

Air conditioning causes car to idle or die.


Depending on whether your car is Injected or Carby induction, The aircon system has an IDLE UP circuit which is supposed to raise the Idle while the Aircon Compressor is engaged. The Compressor cycles on & off to charge the system pressure as required. The Idle up system typically uses an IDLE UP SOLENOID which is usually mounted directly on the throttle linkage at the Carby or Throttle body itself, or a Vacuum Solenoid which switches vacuum to a Diaphram which is connected to a linkage on the Carby or Throttle body itself, or a Vacuum Switch which ports air into the throttle body to raise idle (This type on injected vehicles only). It sounds as if the IDLE UP system has failed or is not adjusted properly. Revving the engine spins the compressor faster thus charging the system sufficiently to dis-engage the compressor, which in turn removes the load from the engine, allowing it to idle again. A simple way to test is to disconnect the Aircon clutch wire (make sure it cannot fall into belt) & switch on the Air with the engine running. The RPM should raise typically around 300 RPM. If it doesn't the IDLE UP is not working. Hope this helps.

2003 Ford Taurus will not rev above 3000 RPM


you have a rev limiter in neutral. Is that when this happens?

Engine RPM/Vehicle Speed Limiter The powertrain control module (PCM) will disable some or all of the fuel injectors whenever an engine rpm or vehicle overspeed condition is detected. The purpose of the engine rpm or vehicle speed limiter is to prevent damage to the powertrain. The vehicle will exhibit a rough running engine condition, and the PCM will store a Continuous Memory DTC P1270. Once the driver reduces the excessive speed, the engine will return to the normal operating mode. No repair is required. However, the technician should clear the PCM and inform the customer of the reason for the DTC.
--------------------------------------------------------------------------------------

Fail-Safe Cooling Strategy The fail-safe cooling strategy is activated by the PCM only in the event that an overheating condition has been identified. This strategy provides engine temperature control when the cylinder head temperature exceeds certain limits. The cylinder head temperature is measured by the Cylinder Head Temperature (CHT) sensor. For additional information about the CHT sensor, refer to PCM Inputs for a description of the CHT sensor. Note: Not all vehicles equip with a CHT sensor will have the fail-safe cooling strategy.
A cooling system failure such as low coolant or coolant loss could cause an overheating condition. As a result, damage to major engine components could occur. Along with a CHT sensor, the fail-safe cooling strategy is used to prevent damage by allowing air cooling of the engine. This strategy allows the vehicle to be driven safely for a short time with some loss of performance when a overheat condition exist.
Engine temperature is controlled by varying and alternating the number of disabled fuel injectors. This allows all cylinders to cool. When the fuel injectors are disabled, their respective cylinders work as air pumps, and this air is used to cool the cylinders. The more fuel injectors that are disabled, the cooler the engine runs, but the engine has less power.
Note: A wide open throttle (WOT) delay is incorporated if the CHT temperature is exceeded during WOT operation. At WOT, the injectors will function for a limited amount of time allowing the customer to complete a passing maneuver.
Before injectors are disabled, the fail-safe cooling strategy alerts the customer to a cooling system problem by moving the instrument cluster temperature gauge to the hot zone and a PCM DTC P1285 is set. Depending on the vehicle, other indicators, such as an audible chime or warning lamp, can be used to alert the customer of fail-safe cooling. If overheating continues, the strategy begins to disable the fuel injectors, a DTC P1299 is stored in the PCM memory, and a malfunction indicator light (MIL) (either CHECK ENGINE or SERVICE ENGINE SOON), comes on. If the overheating condition continues and a critical temperature is reached, all fuel injectors are turned off and the engine is disabled.

Rpm drops down when acu is turned on


Are you turning on the compressor (as in turning on the air conditioning) or just the vent? If you're turning on the compressor and the revs drop, that's normal. The compressor is driven by an engine belt, and when it is turned on, it puts additional drag and load on the engine, causing the revs to drop.

Lose timing condition


There is a valve on the intake manifold that increases the RPMs when the AC is on. Check for a vacuum leak at the hose going from it to the manifold, or the valve may be bad.
