I have a 2001 Hyundai xg300 stock engine. I have replaced the throttle body 2 times an the tps. An the car runs but when pressing the gas it don't move. no response.


Like you said the first two codes are tps related. Check your wire harness and wiring could be shorted to ground or have a broken wire. The third code is for map sensor no response shorted or open circuit.

Idle air control system


Have you used a OBD-II scanner to find your issue? The car will help you find out what is needed to fix it. Remember to clear the settings after fixing something. This will help pinpoint your issue. If the same issue arises then the issue is another part. Read those codes supplied with the unit. It will help eliminate possible multiple problems. I have included what the codes mean in the following link How to Read an OBD II Engine Code Best of luck

P0106


You can try to handle this several ways. The MAP sensor as a stand alone part can be bad. But the Code for the MAP defect is made when other signals do not agree with the MAP values. For instance, the Throttle position is different than what the MAP thinks it should be- you get a MAP Code instead of a Throttle Code. If an O2 reading disagrees with the MAP values, you get a MAP Code instead of a O2 Code.

So as you may be able to start to see, you could replace the MAP and the old one could be good. But if the new MAP kills the Code, the old MAP was probably bad.

The MAP measures absolute pressure in the manifold. This is measured in several ways, pretty much how air pressure should be at the throttle flap compared to upstream and downstream.

The MAP is a simple component, another Expert may be able to say whether "Flashing" any part of the Computer controls will fix this. Some computer parts are "Read Only" , some can be rewritten.
Sometimes something happens to a computer and values are lost.

A better scanner can investigate your engine and actually show the measurements for the different components. Scanners like these can take out the guesswork so a technician knows if the MAP is accurately reading the measurements or not.

You can just get lucky and replace the MAP. Then if it does not help, get a Technician. Clear the computer by disconnecting 1 battery cable for 10 minutes.

Pontiac Aztek 2001 - 3.4l (non-GT); Codes: P0135, P0141, P0420 all O2 + Converter. Ideas on problem?


P0135 bank 1 sensor 1 open or short in wires,bad connections,bad sensor ,or bad ecm. P0141 bank 1 sensor 2 same diag as P0135. P0420 cat below threshold open or short, or faulty Ho2s sensors.you may have several problems. start with sensors circuit if good change sensors if not trace to ecm if reading not right replace ecm if all good replace sensors clear codes retest drive two drive cycles for cat to clear tests. then with no dtcs present test fuel pressure , injectors,then ignition system ,timing valves ,map,maf sensors,throttle sensor,crank sensor cam sensor, compression.

I have this eobd code problem p0105 in my elantra, where those sensors?


P0105 - Manifold Absolute Pressure/Barometric Pressure Circuit Malfunction
The MAP (Manifold Absolute Pressure) sensor is part of the fuel management system. It reacts to changes in engine manifold pressure. The PCM (Powertrain Control Module) monitors the MAP sensor continually to properly run the engine. Changes in engine load require changes in the amount of fuel injected, and timing of the ignition system, etc. An engine under load has more manifold pressure(or less vacuum) than an engine that is coasting. As the load changes, the MAP sensor voltage signal to the PCM changes accordingly. To check the MAP sensor operation, though, the PCM watches other sensors to verify that the MAP sensor is working properly.

For example, the PCM compares the TPS (Throttle Position Sensor) signal to the MAP signal to verify the MAP signal isn't "sticking". If the PCM doesn't see a MAP sensor change immediately follow a change in the throttle pedal sensor, it knows there is a problem with the MAP sensor and sets P0105. Or, if the PCM notices that the TPS indicates the engine is under load, but the MAP signal indicates that the engine is "coasting" it, again, knows there is a problem with the MAP sensor or TPS and sets P0105.

Symptoms of a P0105 check engine light code may include:
* Poor running engine
* Engine runs rich
* Engine won't idle
* Engine backfires through tailpipe
* Engine misfire under load or at idle
* MIL (Malfunction Indicator Lamp) illumination
* In some extreme cases there may be no symptoms other than MIL illumination

Causes: A P0105 DTC could be caused by:
* MAP sensor vacuum hose disconnected or plugged
* Bad MAP sensor
* Bad TPS
* Damaged or problematic MAP sensor connector
* Damaged or problematic TPS connector
* Damaged wiring
* Short to reference voltage on signal circuit of MAP sensor
* Loss of ground to MAP sensor or TPS
* Open on signal circuit of MAP sensor
* Bad PCM

Possible Solutions:
Using a scanner or code reader, turn the ignition on and engine OFF; what does the MAP sensor voltage read? It should be about 4 Volts for sea level. If you are at a higher altitude, it should decrease about half a volt or so for each 1,000 ft. of altitude (this will vary from model to model) Or if you have a separate MAF (Mass air flow) sensor on your vehicle, they are usually equipped with a Barometric pressure reading. If so, the Baro reading should match the MAP reading (they both measure ambient air pressure). If they're roughly equal, then, check for Freeze Frame data of the MAP sensor (if available).

NOTE: Freeze Frame data is the PCM recording a fault when it happens. It captures the readings of the various PIDS (parameter identifiers)available to troubleshoot what happened. It's like a recording of the problem as it happened. At idle a typical MAP sensor Voltage reading should be about a volt, and at WOT (wide open throttle) it should approach 4.5 to 5 Volts. As for the TPS, at idle, the voltage reading is about 1 Volt or less. As the throttle is opened the reading will increase to 4.5 Volts at WOT. Do the two readings make sense? For example, if the TPS reading on Freeze Frame data shows 2.5 Volts (indicating partial throttle) does the MAP sensor indicate a reading that isn't at either extreme? Using the Freeze Frame data (if available) compare the MAP reading to the TPS when the problem occurred. This can help you identify what happened

If you have no access to Freeze Frame data then check if the MAP sensor voltage changes when you apply vacuum to it. You can do this by mouth or a vacuum pump. The voltage should increase as you apply vacuum. If the reading doesn't change as you apply vacuum, make sure there are no obstructions in the hose to the sensor. If the hose is clear, the MAP sensor is usually bad, but it doesn't rule out the following from causing the problem: Does the MAP sensor appear to be stuck at less than .5 Volts? Then:

NOTE: This code shouldn't set if the MAP is stuck at extremely low voltage, however, I'm adding it in because there's no way to know for certain for which vehicles a low voltage condition may set a P0105.

1. Inspect the wiring harness and MAP sensor connector. Repair any damage
2. Unplug the MAP sensor connector. Also, at the PCM connector, remove the MAP sensor signal wire and check for continuity to the MAP sensor connector. If there is infinite resistance, then repair open in MAP signal circuit. If the signal wire has continuity to the MAP sensor connector, then check for 5 volt reference voltage to the connector and a good ground. If both are present, then re-install all removed wiring and replace the MAP sensor.

Does the MAP sensor appear to be stuck at full 4.5 voltage? Then:
1. Inspect the wiring harness for damage. Repair as needed
2. Remove the MAP sensor signal wire from the PCM connector. With a voltmeter measure the voltage with KEY ON ENGINE OFF. Is there 4.5 Volts? If so, unplug the MAP sensor and recheck. If it is still present, then repair short between the signal wire and 5 volt reference wire.
3. If unplugging the MAP sensor causes the voltage to disappear, check that the ground is intact. If it is, then replace the MAP sensor due to internal short.

MAP sensor codes include P0106, P0107, P0108 and P0109 .


LOCATIONS:
Manifold Absolute Pressure (MAP) Sensor: The MAP sensor is located against the firewall to the left side of the engine.
Barometric Pressure Sensor: This sensor is installed on the VAF sensor; Volume Air Flow Sensor Is located in the air intake plenum assembly.

Hope this helps.

P0500 and P0501 are vehicle speed sensor codes P1529 I can not find in any of my data bases. if you are using a generic scanner/code reader it may be a false display or for some reason it's not listed in my reference materials. I have 4 different sources 1 being factory material?

Hyundai Elentra 96, struggles to start.....dealer wants to replace cam shaft chain, crank shaft sensor, transmission range sensor +.....


Take/Tow your vehicle to an authorized Hyundai dealership and pay the diagnostic fee... they will tell you exactly what the problem is and the cost of parts/labor to fix it... at least this way you'll know what the problem is and what's required to fix it.Go to www.hmaservice.com and register( Vehicle by VIN). Afterward, you have access to shop manuals, service bulletins, wiring diagrams, etc. about your vehicle.

2001 hyundai elantra idling high


weeeeiiirrdddd. i have a 2001 hyundia elentra gls, and my third cylinder is misfiring as well. my car also revs constantly on idle and in between shifting. it will flutter between 2-3000 or it will just stay at 5000. i replaced my plugs and wires to no fix with my cylinder. autozone also told me that it sounds like my throttle position sensor needs replaced, but every part they try to sell me will not fit and they swear up and down this is the right part...
