Injection system failure light comes on and engine power reduced -. If the firing order is changed or adjusted, the ignition from the spark plug is delivered at the wrong time and the engine functions poorly or does not run. The throttle position sensor responds to the throttle valve movement. Had it analized and fault code P0220 Accelerator pedal position 2 signal improbable showed up. Shops report a pattern failure in the electrical harness to these sensors. Enter the 5 character trouble codes in the search box and submit the search. Free play is usually not repairable especially on non-adjustable sensors meaning that both the sensor and the throttle body are best replaced.
Came on there tonight again constant saying same message. The throttle position sensor has the two sensors. Plenty of posts on this and I think Qinteq posted up some pictures. Car and truck exhaust contains toxic gases such, so if the inside of your car as if you were standing behind your car, get out and get it fixed. If i put my feet down the car goes but it leaves a cloud of black smoke behind. Pull over, retighten it, and take a look at the cap to see if it has any cracks in it. Also note that both sides of the graph should be equal, meaning that the side of the curve denoting the throttle opening should have the same angle as the opposite side of the curve that denotes the throttle closing.
Ive got 2 keys tried both also tried moving pickup ring around the key. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. Update on how things are going. The throttle position sensor has the two sensors. Second thing was the engine is more shaky and loud. Now i can only do 500. If it does, repair or replace the affected connector.

The currently selected is for the Cadillac makes. Don't be shy, come join us! If your spark plugs look good, problems with your ignition system can also preventing a spark. The car has only started once since it stop 3 weeks ago. I have a 2005 Stilo 1. I pulled the plug apart cleaned the pins, stuck it back together and have never had a problem since.
If it code persists, perform resistance, reference voltage, ground, and continuity checks on all wiring and connectors. The information contained on this site is presented for informational purposes only. It is like runing out of fuel. Replace the sensor, and retest the system. The judges the current opening angle of the throttle valve from these signals and the controls the throttle control motor to make the throttle valve opening angle properly in response to driving condition. I assume sensor 1 would be accelerator pedal. With throttle closed, voltage should be about.
However in recent times it has developed a serious intermittent fault and have had it in two garages so far and neither have been able to diagnose my This is why its important to see the actual fault code P0120 Throttle Pedal Position SensorSwitch A Circuit Malfunction P0121 ThrottlePedal Position SensorSwitch A Circuit RangePerformance Problem P0122 ThrottlePedal Position SensorSwitch A Circuit Low Input P0123 ThrottlePedal Position SensorSwitch A Circuit High Input P0124 ThrottlePedal Position SensorSwitch A Circuit Intermittent p0220 ThrottlePedal Originally Posted by Davren This is why its important to see the actual fault code P0120 Throttle Pedal Position SensorSwitch A Circuit Malfunction P0121 ThrottlePedal Position SensorSwitch A Circuit RangePerformance Problem P0122 ThrottlePedal Position SensorSwitch A Circuit Low Input P0123 ThrottlePedal Position SensorSwitch A Circuit High Input P0124 ThrottlePedal Position SensorSwitch A Circuit And for those of us unfortunate enuff to have need of them. So you should chech it on our car models. In some applications, there may be additional sensors and devices fitted to act as back-ups should a primary component or sensor fail. The throttle position sensor has the two sensors. These sensors are a kind of potentiometers which transform the throttle valve position into output voltage, and emit the voltage signal to the Engine Control Module In addition, these sensors detect the opening and closing speed of the throttle valve and feed the voltage signals to the. It goes well when i put my foot down for 5 second and after that i can feel a lag for 5 sec and then goes again.
The throttle position sensor responds to the throttle valve movement. Thanks in advance Hi there. The error as well the behavior. We are not responsible for any actions you take on your vehicle. The throttle position sensor responds to the throttle valve movement. Drives great then goes in limp home mode and loose connetion on dash. So what are you waiting for? If you got them the wrong way round they caused similar symptoms.
If you have any doubt as to repairs on your vehicle, please contact your technician. Be sure to check the reference voltage at the connector to the pedal Hall sensor as well. The error as well the behavior. It takes at least two turns of the ignition to get it going. The most common symptoms of code P0220 are much the same on all vehicles, although the severity of some symptoms may vary from vehicle to vehicle.
Do you anyone already experienced this issue and solve it? The converter is essentially an afterburner that cleans up the exhaust after it exits the engine. Marcus greg This up your alley. With multiecu scan i could find 2 errors. QinteQ thanked for this post Last weekend I had a problem with my 2001 C240 and the accelerator pedal or so I thought from troubleshooting and reading the W203 forum. What are the common causes of code P0220? So you should chech it on our car models. If this is not the case, wiggle all connectors including the connector on the pedal Hall sensor around and see if the reading on the scanner changes or fluctuates.
A typical reading at idle is often zero volts, but the throttle opening should not exceed about 2 degrees. Step 1 Record all stored codes and available freeze frame data for future reference. Also the car paint ought to be in good condition because that reduces the chances of rust taking over the body of your car. This system tests the fuel system to make sure it is not leaking fuel vapors into the air. One was p0220-accelerator pedal sensor 2 and the other one is p0704-clutch signal.
