Some cars use both an accelerator pedal position sensor on the pedal and one TPS sensor on the throttle body, while some cars only have a TPS sensor on the throttle body. Suzuki  |   C . The accelerator pedal sensor transmits the position of the accelerator pedal to the engine control unit. I remember when GM electronic throttle body equipped vehicles started rolling into the auto repair shop, where I worked, and feeling a bit nervous about having to diagnose them (to later realize just how easy it is to diagnose them!). IMPORTANT: The image, above, shows you the front of the connector just to make it easier to identify the circuit you need to test. The next step is to verify that Accelerator Pedal Position (APP) Sensor 2 is being fed with ground. Connect the red multimeter test lead directly on the battery's positive terminal using a battery jump start cable. This voltage signal starts high (around 4 Volts DC) when the pedal IS NOT being depressed and decreases (to around 2.9 Volts DC) as you depress the pedal. Turn the key OFF. Accelerator pedal position sensor is mounted on the throttle body and it has the 2 sensors to detects the accelerator position and a malfunction of the accelerator position’s own. Don’t attempt this if you’re uncomfortable working with electricity, as removing the wrong fuse or cable from your battery could be dangerous. This is where a Wire Piercing Probe comes in handy since it'll let you easily access the wire inside the insulation (to see what this tool looks like, click here: Ground the multimeter's Black lead directly on the battery's negative terminal. Based on this information, the load requested by the driver can be implemented immediately. Rodney Dangerfield, Home  |   If the accelerator position sensor stops working then the ECM won't have correct information about what kind of pressure you are putting on the gas pedal. With the sensor, there come the accelerator pedal position sensor problems as well. Using the one chennel on the lab scope, probe the APP signal 1 circuit at the PCM harness connector. The importance of a TPS sensor can be emphasized as it can affect the gas mileage and engine response. And so, I want to assure you that the key, to successfully diagnosing an Accelerator Pedal Position (APP) sensor problem on your own, is remembering that the APP Sensor(s) inside the Accelerator Pedal Position Assembly are just potentiometers (like the old style Throttle Position Sensors on Fuel Injection Systems with a throttle cable). Copyright © 2009-2020 Abraham Torres-Arredondo All Rights Reserved. Turn the ignition switch to on. If your multimeter still does not register 10 to 12 Volts in this circuit, then you've found the cause of the APP Sensor 2 Diagnostic Trouble Code (DTC). The ability to smoothly accelerate down the road while using an adequate amount of energy is attributed to the accelerator pedal position (APP) sensor. Unfortunately, this part can't be repaired, so when a certified mechanic diagnoses that there is a problem with this device, you'll have to replace the accelerator pedal position sensor. there's 2 sensors contained in the pedal sensor, and one on the throttle plate shaft, more often than not, it's the pedal sensor, and if you replaced that, it's the other one or a loose connection. than wait at least 2, if not 3 minutes, for the system to reset. The signal on channel 2 is offset by 0.75 V to the signal from channel 1 over the complete range of the sensor.

At this point the check engine light starts blinking quickly With an accelerator pedal position of 0 degrees, potentiometer 1 may output a signal of 0.5 volts and potentiometer 2 may output a signal of 4.5 volts. The next step is to check that APP Sensor 2 is creating the correct pedal position signal. If you don't know the vehicle, dont post! CASE 2: Your multimeter DID NOT register 10 to 12 Volts. You should see about 3.8 Volts to 4.0L Volts DC. 2. Question type: Maintenance & Repair. When testing the circuit, you should back-probe the connector or probe the wire (with a wire-piercing probe), or you could damage the metal female terminal! I have heard both but only done the positive one. If all is OK, your multimeter should register 10 to 12 Volts. On this page we will explain the principle according to which modern pedal travel transmitters operate, and which symptoms indicate a fault in this sensor. Mitsubishi They should be well sealed and free from cracks or tears. Observe your multimeter's voltage DC reading. The APP sensor, which is fixed to the throttle body of the 'electronic throttle control system with intelligence' (ETCSi), monitors the position of the throttle pedal. The Accelerator Pedal Assembly is not connected to the throttle plate via a cable (like in the good ole' days).
