What is P050B : Engine Error code Causes Explained
This Tutorial covers the P1153 engine trouble code, which usually indicates a problem with bank 2 oxygen sensor 1. The sensor may be producing inaccurate values, compromising air-fuel mixture and horsepower.
How to Identify a DTCs Number
The DTC (Diagnostic Trouble Code) P050B refers to an issue with the Engine Control Module (ECM) detecting a problem with the Idle Air Control System.
Understand that the trouble codes (DTCs) are 5 characters: 1 letter, 4 numbers. P-Powertrain indicates the fault code’s location. Generic or manufacturer-specific codes are indicated by the first digit. The second digit denotes the subsystem (7=transmission). The last two numbers describe the issue.
This issue may occur during cold starts when the engine is not reaching the correct idle speed after being started.
Causes of P050B Code:
- Faulty sensors:
Engine coolant temperature sensor, CKP sensor, CMP sensor, throttle position sensor. - Electrical issues:
Open or shorted circuits, loose connectors related to the sensors - Vacuum leaks:
Large leaks in the intake manifold system - Air filter problems:
Clogged air filter restricting airflow - Battery issues:
Low battery voltage affecting the starting power
Risk Level of P050B Error Code:
The “High Risk Level” warning typically appears when the issue related to the P050B code could significantly affect the vehicle’s drivability and engine performance. It’s essential to take immediate action.

FAQ’s
What is the P050B engine error code?
The P050B code indicates a problem with the idle air control system, specifically related to the engine’s idle speed control during cold starts.
What causes the P050B engine error code?
The P050B code can be triggered by a faulty idle air control valve, dirty throttle body, or a malfunction in the engine control module (ECM) that regulates idle speed.
What is the risk level of the P050B error code?
The risk level of the P050B code is moderate. If not addressed, it can lead to unstable idling, rough starts, and may affect the overall engine performance.
