What causes the P2128 code? Did you complete the replacement? Also make sure the charging system is good. It happens every once in a while when starting the car, especially if you have to crack the throttle to start the car. Damage to the control module may occur due to excessive current draw. Did you find and correct the condition? Regardless of how you approach it, you should get this fixed right away. However, an oxygen sensor is easy to replace on many cars and is usually detailed in the owner's manual.
Is the resistance less than the specified value? Refer to and in Wiring Systems. Chevrolet Impala P2127 if your catalytic convertor fails completely, you eventually won't be able to keep the car running. However, this code can also be generated by the installation of aftermarket equipment that is tapped into the wrong wire radio, remote starter, radar detector, etc. Other times it happens under a hard acceleration in 1st gear, if tires spin and I am off the throttle then back on the throttle. What are the causes of the P2138 code? Do not ever try to manually open the butterfly valve in an electronic throttle body with your hand or any other tool. Pull over, retighten it, and take a look at the cap to see if it has any cracks in it.
It knows where each voltage will be as it skews back and forth. What the P2128 code means The pedal position sensor is a hall effect style of sensor and it should change its voltage according to the angle of the gas pedal assembly. How serious is the P2138 code? It is important to distinguish the two with an appropriate diagram when diagnosing this trouble code. Then dry out the connector, apply dielectric grease and reseat the connector. If you find water in the connector, locate the source of the leak.
Did you find and correct the condition? The car was working fine for a while Paul, I had this problem on a supercharged car a few months back. Water can leak into the connector from clogged sunroof drains, A-pillar leaks, or windshield or cowling leaks. When these lights come on I have to immediately pull over and turn my car off if I try to drive it it jerks and I can't go above 20 mph. The pedal position signal is converted to pedal travel degrees rotary angle by the. With that said, I would recommend to anyone that has a P2138 trouble code stored to have the issue handled immediately. If not, a code P2128 may be set.
In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. The determines if a signal is incorrect by calculating where it should be, inferred from the other signals. Need help with a P2138 code? The P2138 trouble code may be stored in the computer along with a check engine light. If I am late to work due to the fact that my car is not accelerating properly or stalling on the side of the road, I am not going to be very happy. If you know where the sensor is, you only have to unclip the old sensor and replace it with a new one. Step Action Values Yes No Schematic Reference: Connector End View Reference: or 1 Did you perform the Diagnostic System Check - Vehicle? There are 2 pedal position signals in the sensor.
When the check engine light comes P2128 code on the first you should check is the gas cap. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver. If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. One reads 0-5 and the other basically reads 5-0. Some mechanics have replaced the wrong sensor unknowingly. Continue driving and see if the check engine light turns off.
So you should chech it on our car models. What repairs can fix the P2128 code? The 2 pedal position signals make sure the receives a correct input even if 1 signal has a concern. The engine control module will supply the pedal position sensor with what is known as a reference voltage. All of the necessary airflow tables have been changed If you have another throttle body try swapping it. I guess the diagnostics where doing there job! Howard, I have all that information although I do appreciate you copying and pasting it for me. And yes that was the only code that come up. The lean fuel mix error may be accompanied by rough idling, engine misfires, hesitation during acceleration and overall poor engine performance.
All you need to do is take the old one off and screw on the new one. Review the electrical schematic and diagnose the shared circuits and sensors. It knows where each voltage will be as it skews back and forth. . This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time. This randomly started happening one day with no tune changes. What repairs can fix the P2138 code? ©, 2015 Rick Muscoplat Save.
One reads 0-5 and the other basically reads 5-0. If you've already made it to the store, you might as well just replace it. Now don't ask yourself; What should you do with P2138 code? Did you find and correct the condition? This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time. Did you complete the replacement? The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. The numbers below refer to the step numbers on the diagnostic table.
