P2128 2006 Toyota Camry Code - Throttle Pedal Position Sensor/Switch 'E' Circuit Input High
Quick Answer
The Accelerator Pedal Position (APP) sensor is mounted on the accelerator pedal to detect the angle of the accelerator pedal. Common causes include Faulty Accelerator Pedal Position (APP) Sensor, Accelerator Pedal Position (APP) Sensor harness is open or shorted, Accelerator Pedal Position (APP) Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2128 2006 Toyota Camry Description
In the accelerator pedal position sensor, the voltage applied to terminals VPA and VPA2 of the Engine Control Module (ECM) changes between 0 V and 5 V in proportion to the angle of the accelerator pedal. The VPA is a signal to indicate the actual accelerator pedal angle and is used for the engine control. VPA2 is used to detect malfunctions of the sensor itself.
The ECM monitors the accelerator pedal angle from VPA and VPA2 signal outputs, and controls the throttle motor based on these signals.
What are the Possible Causes of the DTC P2128 2006 Toyota Camry?
- Faulty Accelerator Pedal Position (APP) Sensor
- Accelerator Pedal Position (APP) Sensor harness is open or shorted
- Accelerator Pedal Position (APP) Sensor circuit poor electrical connection
- Faulty Engine Control Module (ECM)
How to Fix the DTC P2128 2006 Toyota Camry?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

2004 camry, 2.4, acceleration pedal goes halfway to floor before eng starts to rev. Appears to be in limp mode. Threw code p2121 (tps) code. After I cleared the code, cel immediately came back, this time with p2121 and p2128. Which do you think is the cause? Did the tps problem cause the petal code or vice versa?
-
Unfortunately I haven't had that problem before, but according to a national database of repairs for the 2004 Camry, the most common cause of the problem when you have both codes, P2121 and P2128, is the Accelerator Pedal Position (APP) Sensor, on the acceleration pedal.
