Product Questions & Answers
Q:Is this part the same as a MAP Sensor?
Diana R.
A:BEST ANSWERHi Diana, I'm happy to be able to assist you. The turbo boost sensor (or TBS) is similar to the MAP (manifold absolute pressure) sensor. The only difference is the application. Naturally-aspirated engines will normally use a MAP and MAF sensor. If interested in this part, click on the link below to place an order while supplies last. I hope this is helpful.

P0237 Code: Turbocharger / Supercharger Boost Sensor “A” Circuit LowDiagnostic trouble code (DTC) P0237 stands for “Turbocharger/Supercharger Boost Sensor “A” Circuit Low.” This code is logged when the powertrain control module (PCM) detects an incorrect signal from the boost pressure sensor.
P2563 Code: Turbocharger Boost Control Position Sensor Circuit Range / PerformanceA turbocharger boost control position sensor constantly monitors the turbocharger. If the sensor doesn’t send the right signal or sends an abnormal signal to the PCM, the computer will log a P2563 code.

What Does the P2563 Code Mean?
P0236 Code: Turbocharger / Supercharger Boost Sensor “A” CircuitIn non-turbo engines, the downward motion of the pistons during the intake stroke creates a vacuum in the intake manifold. This vacuum is what draws the air-fuel mixture into the combustion chamber.
