P0226
Throttle/Pedal Position Sensor/Switch C Circuit Range/Performance
DTC P0226, sometimes indicated as P022600 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing throttle/pedal position sensor/switch c circuit range/performance.
The throttle/pedal position sensor/switch C is responsible for reading the position of the accelerator pedal. If this sensor experiences a problem, the Range/Performance light will come on, and the engine may not run as smoothly as it should.
There are several things that can cause this issue, including a faulty sensor, a wiring problem, or a problem with the engine control system. If the Range/Performance light comes on, it is best to have a qualified technician inspect the vehicle to determine the cause.

- P0226: Throttle/Pedal Position Sensor/Switch "C" Circuit Range/Performance
- P0226: TPS/Pedal Position Sensor/Switch C CKT Range/Performance
- P0226: Throttle position (TP) sensor C/accelerator pedal position (APP) sensor C – range/performance problem
- P0226: Throttle position (TP) switch C/accelerator pedal position (APP) switch C – range/performance problem
- P0226 00: Damage to the damping sensor: throttle damage or damping sensor: acceleration pedaphy
- P0226 00: Throttle position (TP) sensor C/accelerator pedal position (APP) sensor C - range/performance problem
- P0226 00: Throttle position (TP) switch C/accelerator pedal position (APP) switch C - range/performance problem

2001 VOLKSWAGEN NEW BEETLE with 55000.0 miles
Driving at 65 mph, engine speed 2200 rpm, vehicle suddenly decelerates to engine speed 1200 rpm (35 mph). Approx 5-10 seconds later the mil ("check engine") light comes on solid and the glo-plug lamp blinks. Obd-ii diagnostic code "P0226" (throttle position sensor) code was subsequently read. Throttle control may be momentarily regained by turning vehicle ignition off and back on in order to maintain speed (observing care that road is straight so that steering wheel lock does not lock up). Failure may re-occur within 50-100 yards, repeatedly requiring ignition turn-off/turn-on sequencing for 'bursts' of throttle function between failures being careful to try to avoid steering wheel lock. Alternative to recovery from loss of foot throttle is to quickly engage cruise control (limiting acceleration is limited to 1 mph 'clicks'). Vw of america ([xxx] 3-mar-03, 1210 pst, - cust. Care #30108450) denies knowledge of a problem with throttle position sensors and vehicle defaulting to 1200 rpm 'limp mode'. Lithia motors (medford, or - vw sales & service) has also noted the P0226 ("throttle position sensor") code when vehicle was taken to service department for diagnostic trouble investigation but unable to correlate the "throttle position sensor" code with 1200 rpm engine limitation and loss of throttle function. Independent service shop says that throttle position sensors have been modified and are on back order and that the tps in this vehicle (vin # [xxx]) fails to provide proper signal ("drive-by-wire" throttle) at between 7% and 17% of foot throttle actuation. Problem has occurred approx. 100-200 times since first noted on 19-feb-2003. Very curious that parts have been modified and are back-ordered when there is "no known problem" and vw and their dealers cannot correlate an obd-ii "P0226" code with this hazardous vehicle control failure. *nlm information redacted pursuant to the freedom of information act (foia), 5 u.S.C. 552(b)(6).
