Code No. Check code No. P accelerator pedal position sensor main circuit low input Refer to. P accelerator pedal position sensor sub circuit low input Refer to. Engine-ECU checks the accelerator pedal position sensor output signal characteristics for abnormal conditions. Ignition switch is "ON" position. Change of accelerator pedal position sensor main output voltage per 25 milliseconds is less than 0. Voltage obtained with the formula given below is more than 0. Throttle opening degree is restricted. Throttle opening degree position is in default position if accelerator pedal position sensor sub fails. Failed accelerator pedal position sensor Harness damage in accelerator pedal position sensor circuit or loose connector contact Failed engine-ECU. STEP 1. Perform resistance measurement at accelerator pedal position sensor connector.

I will not re-install it as this could be a potential hazard. My father in law looked at the battery and felt that the negative terminal looked a little corroded and since we were out of ideas and suggestions, we might as well drive down to the auto store and pick p2138 mitsubishi a new terminal connector and replace it. Engine-ECU checks the accelerator pedal position sensor output signal characteristics for abnormal conditions, p2138 mitsubishi, p2138 mitsubishi.

Advertiser Disclosure. The voltage readings going to the Engine Control Module ECM from the throttle body position sensor and accelerator pedal position sensor do not match each other. On older vehicles, the throttle body was connected to the accelerator pedal via a throttle cable which was a mechanical link between the two. When you pushed the accelerator pedal the throttle body opened, simple as that. As vehicles became more powerful, emissions controls became stricter and better fuel mileage was a requirement, there needed to be a way for the Engine Control Module ECM to control the throttle more precisely. Thus, the drive by wire system was introduced. In this system, the accelerator has a sensor on it that detects how hard you are pressing on the accelerator pedal, and based on the information the ECM receives it commands the throttle body to open based on your accelerator input. This system can also be used for traction control; if the ECM sees that the wheels are slipping, it can limit throttle opening in order to gain control of the vehicle. It may require the vehicle to be towed to a repair facility.

In this video, our mechanic breaks down the P code, its symptoms, including poor acceleration and reduced power mode, and shows you how to diagnose the potential causes so you know what to do to clear the code. Want to watch more videos like this? Visit our video library for thousands of automotive diagnostic and how-to videos. As our mechanic explains in the video above , a gas pedal has two APP sensors to essentially serve as fail-safes for each other in case one triggers an error code. He uses an OBD-II scan tool to look at the data for both sensors to see whether the sensors are working normally. You can see if the data correlates by watching it on your scan tool as you press the gas with your car parked. We recommend addressing the issue causing code P as soon as possible. If the data changes, that indicates the issue is stemming from the pedal itself and not the sensor wires. You can also watch the data being graphed while you wiggle the wires to see if the data changes, which would indicate a wiring or connector issue is triggering P

Perform resistance measurement at accelerator pedal position sensor connector. The dealer refused to test the voltage coming through the wires as the workshop manual suggests because their little MUT-II scanner gave them enough information to convince them it was the sensor. I am going to pull apart the connectors to both the sensor and throttle body today and clean them and apply dielectric grease to them as instructed by another member over PM. I feel like I would have more issues and I have done enough google searching to find this to be a common problem with outy's and ralliart lancers. Go to Step 8. Good Luck, I wish you the best. Throttle opening degree is restricted. After changing the APP sensor the problem still persisted. STEP 8. Garage Speck. STEP 5. Go to Step It was the ECU. I believe it's an indication that the redundant pedal sensor is not reading the same or the transmission and the engine don't agree Has anyone seen this problem? They refused to do a voltage check on the pins of the sensor as the stickied workshop manual describes.

That connector is known to get fouled from corrosion. STEP For a better experience, please enable JavaScript in your browser before proceeding. I honestly am not convinced my computer is the problem. At this point we reviewed the Edmund's link above and began scouring the workshop manual to find the connectors referenced in the description but didn't have any luck. STEP 1. Rather than changing a whole bunch of parts they should be more helpful. STEP 9. I have since replaced my throttle position sensor with 2 separate brand new sensors from the dealer, both of which have done nothing to fix the code. I feel like I would have more issues and I have done enough google searching to find this to be a common problem with outy's and ralliart lancers. Recommended Communities. It was slightly over filled. Throttle opening degree is restricted. Go to Step 9. Coupled with a timing belt change and a few other repairs, I am exceeding the estimated market value of the vehicle and I am in a real bad spot.
