What Does P0512 Mean? Starting a car is easy enough: put the key into the ignition and turn. However, the actual process behind this task is far more complicated. Mechanical keys are paired with resistors and radio transponders with unique codes. This last part is true with today’s push-button ignition systems. P0512 codes are only ever triggered in this type of vehicle. The engine immobilizer system in a vehicle must be programmed to detect the transponder. Essentially, the transponder gives off a signal that the immobilizer can recognize with the help of a tiny antenna. Once it does this, the driver only needs to step on the brake pedal and press the start button to bring their vehicle to life. If it isn’t able to detect this signal, yet an attempt is made to start the automobile, the immobilizer may lock out the starter and trigger the P0512 code. engine code P0512P0512 fixobd P0512dtc P0512obd code P0512obd2 P0512P0512 car codediagnostic code P0512car code P0512check engine code P0512fehlercode P0512P0512 fiatcodigo P0512codigo falla P0512P0512 kody b??dówcodigo de falla P0512 What are the common causes of P0512 ?

How do you troubleshoot P0512 ? There are currently two main types of cylinder deactivation used today, depending on the type of engine.

In their collapsed state, the lifters are unable to elevate their companion pushrods under the valve rocker arms, resulting in valves that cannot be actuated and remain closed.
