Home FIATP0243 FIAT DTC P0243 Make: FIAT Code: P0243 Definition: Turbocharger-Supercharger Wastegate Control Circuit Description: The base Turbocharger boost pressure is managed by the mechanical Wastegate. The Wastegate is a spring loaded mechanical valve that is normally open, allowing the exhaust gases to bypass the turbine inside the ...

2024年10月21日 · The P0243 code is an OBD-II trouble code that indicates a problem with the turbocharger wastegate solenoid “A.” This component plays a crucial role in regulating boost pressure produced by the turbocharger.

2020年7月5日 · What are the common symptoms of OBDII code P0243 (Turbo/Super Charger Wastegate Solenoid 'A')? - Common symptoms include decreased engine performance, reduced boost pressure, engine stalling, and the activation of the Check Engine Light.

OBD2 Code P0243 Fiat definition: The PCM monitors the supercharger (boost) bypass (SCB) solenoid circuit for an electrical failure. The test fails when the signal moves outside the minimum or maximum allowable calibrated parameters for a specified SCB solenoid duty cycle (100% or 0%) by PCM command.

If you’re dealing with a P0243 code due to turbocharger wastegate solenoid issues, the problem likely involves a malfunction in regulating boost pressure. Essential steps include using a DVOM to test the solenoid, checking for damaged wiring, …

2018年9月13日 · OBD II fault code P0243 is a generic code that is defined as “Turbocharger (TC) wastegate regulating valve “A” – circuit malfunction, and is set when the PCM (Powertrain Control Module) detects a malfunction in the control and/or signal circuit of the valve that regulates the operation of the turbocharger wastegate.

2022年3月14日 · The P0243 stands for “Turbocharger/Supercharger Wastegate Solenoid “A”. It’s triggered when the PCM cannot control the solenoid and its wastegate. Some issues that could set the code include a bad wastegate solenoid, issues with the wastegate’s control/signal circuits, or a faulty PCM/ECM.

If all tests have passed so far, and you continue to get a P0243 code, this would most likely indicate a failed wastegate/boost pressure control solenoid, although a failed PCM could not be ruled out until the solenoid had been replaced. If unsure, seek assistance from a trained automotive diagnostician.

2020年7月5日 · Code P0243 Description This fault code is stored in the Engine Control Module (ECM) when a fault is detected with the wastegate control solenoid circuit. The purpose of the control system is to limit the boost pressure to allow for optimum performance without the risk of engine damage due to excessive boost pressure.

I got CEL recently when car is running, code p0243 and p0034. Maybe there are some problems with turbocharger bypass valve or control circuit or turbocharger wastegate solenoid has an open or short circuit. Since i got code, there was no apparent loss of power, but doesn't speed up smoothly like before.
