Harnessing the Potential of P0123 A Comprehensive Tutorial

Get a TPS wiring harness rewire kit as suggested and try that first. If it doesn't correct the issue replace the TPS sensor. Code reads 0123 - Throttle/Pedal Position Sensor/Switch A Circuit High Input. Along with this code I have some downstream sensor circuit codes. P0123 - Throttle/Pedal Position Sensor/Switch Circuit High has been detected. Van runs great. No noticeable issues. The problem is likely with the TPS wiring. Check the voltage at the TPS (refer to a service manual for your vehicle for specific information). Code P0123 TPS sensor ... Have you tried disconnecting the TPS sensor connector and checking to see if it's clean and tight? It's a quick start ... I got the code P0123 so I figured I'd check the Tps sensor voltage and it was reading fine (has power, signal, ground) also checked it with throttle open and ... Usually if the TPS or APPS has issues it throws the 2121 or 2122. The TPS has two circuits. One is the 5 volt for actual position to control the RPM. The common causes of TPS errors (apart from aftermarket throttle bodies and aftermarket TPS sensors): - TPS sensors go bad, especially in ... I've got a 2014 SE hatchback with a manual transmission that is throwing P0123 & P0223 codes. I've installed 2 different throttle bodies as well as a new pedal. The TPS sensor should produce around .5v at full closed throttle plate and around 4.5v with the pedal all the way down.
