And thanks for any kinda help. YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle. P2173 code definition Throttle Actuator Control System - High Airflow Detected What the P2173 code means Code P2173 means that there is a vacuum leak somewhere in the intake system or one or more of the sensors that monitors intake pressures has malfunctioned. Im going to call the tuner in a few hours and see what he says. This should be used with the motor off and connected to a vacuum port. If a technician fails to find the leak, he or she may suspect a sensor problem and spend a lot of time testing each suspected sensor one at a time, only to find that they are all good. In such cases, other components like the catalyst can temporarily compensate for the part that is broken however, these other components can only do double duty for so long before they, too, begin to malfunction.
Common mistakes when diagnosing the P2173 code A thorough check for vacuum leaks is often harder said than done. If your spark plugs look good, problems with your ignition system can also preventing a spark. It is this system that will detect excessive air flow into the motor. Only when I seem to be cruising tho, Not under acceleration. But i want to make sure its not an easy fix before I waste 500. If any other systems should leak vacuum, a vacuum leak will occur.
This Diagnostic Dilemma revolved around how a vacuum leak could simultaneously be so large and so intermittent. So you should chech it on our car models. Or, you can start on the electrical side by doing a voltage drop on both the power and ground connections for the fuel pump. The improper timing of the explosion sometimes pushes the cylinder the wrong direction or interferes with the turning of the crank. In the case of a very large vacuum leak, which is likely to make the car un-drivable, burnt valves in the head is possible. Code Set Parameters In the event that an unexpectedly large amount of air is suddenly introduced into the of throttle actuator control system, a trouble code will be stored and a service engine soon lamp will be illuminated.
The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. If the plug wires are out of sequence, the explosion occurs at the wrong time. Also, The cars idle rpms would raise then lower, raise then lower between 750-950 over 3 sec constantly. The data before and after might be useful or useful down the road when ur car starts acting up. But the charcoal can only hold so much vapor.
Since a variation of 0. You'll be glad to know that your vehicle is equipped with an early warning system that could save you time, money, and fuel in addition to helping protect the car! For this reason lightly spraying at suspected areas is necessary to isolate, where there is a possible intake leak. Im sure taking it in to be dyno tuned will solve this issue. I carefully listened to his story and tried to make sense of it. This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time. You should also check that the spark plug gap is set properly. It was my throttle body! Drive-by-wire throttle body components are typically not serviceable as individual parts and require replacement of the entire throttle body.
The converter is essentially an afterburner that cleans up the exhaust after it exits the engine. I asked my client if he could see the hole through the firewall. Finger cross, and ill repost what happens. During this fruitless test session, the owner struck up a conversation about how he had loaned his car to his daughter for one month in a city 125 miles away. These control modules may include but are not limited to the transmission control module, the body control module, the antilock brake control module, the instrument panel control module, the fuel injection control module, the turbo control module, the anti-theft module, the cruise control module, the traction control module, proximity alert module, and the climate control module. Any how, think was thinking.
Follow correct Self-Test procedures, refer to Section 2, Quick Test. If this 5 volt reference is compromised by a short to ground or power, the results are unpredictable. The leak detection pump is part of the evaporative emissions system. Lightly spraying a mist of starter fluid, brake cleaner or carburetor cleaner in suspected areas will often reveals a vacuum leak. P2173 Peugeot Possible Solution: Gasoline engines use spark plugs to cause an explosion of fuel within the cylinder. I pull up to the dyno shop, and there is dodge viper racing cars every where in this shop, so im thinking im def in the right place to get tuned :0. He then inserted a finger through the hole and let out another war whoop.
Obviously, this leads to an unsuccessful repair. The lean fuel mix error may be accompanied by rough idling, engine misfires, hesitation during acceleration and overall poor engine performance. P2173 Fiat Possible Solution: The crankshaft sensor signals the fuel injection computer or the ignition control when the cylinders are firing. In the case of a broken wire, the sensor never sees the voltage and the computer assumes a major fault. After hurriedly connecting my scan tool, I discovered that, as before, the engine was running exactly at 1,600 rpm, under a very lean operating condition.
If the problem is not enough fuel, the culprit may be dirty injectors or fuel filters, a weak fuel pump or a leaky fuel pressure regulator. Continue driving and see if the check engine light turns off. Bought a new throttle body, installed it. As the pressure builds in the intake system, smoke will be forced out of any vacuum leak in the entire system. All sensors use a 5 volt reference instead of the unsteady 13 to 15. What you want to look any conditions that might cause ignition misfire, an overly rich or lean fuel condition, or loss of compression. It is possible on some vehicles to only exhibit mild symptoms and a Check Engine Light, but different codes are usually set.
This machine creates smoke under pressure that it injects into the intake manifold and all the vacuum lines connected to it. I need new Tires Soon!! Pull over, retighten it, and take a look at the cap to see if it has any cracks in it. Spinning tires in first and second. For this reason the technician should expect to find a vacuum leak. What repairs can fix the P2173 code? These can range from a faulty spark plug lead, shorted kill switch or flywheel key damage.
