OBD-II Diagnostic Trouble Codes (DTCs) are accessed using a generic scan tool connected to vehicle Data Link Connector (DLC). MINI trouble codes can be accessed using BMW’s GROUP TESTER ONE (GT-1) or DISplus hardware system. These are often referred to as BMW SCAN TOOL. The OBD-II connector is located in driver’s footwell to left of…

P0251 Fuel metering valve control circuit open DETECTION CONDITION •  The PCM monitors the input voltage from the fuel metering valve.

POSSIBLE CAUSE •  MAP sensor malfunction •  Connector or terminal malfunction •  Open circuit in the wiring harness between…

P0238 Manifold absolute pressure (MAP) sensor circuit high input DETECTION CONDITION •  The PCM monitors the MAP sensor signal. If the voltage at PCM terminal 234 remains high, the PCM determines that there is an MAP sensor circuit problem. POSSIBLE CAUSE •  MAP sensor malfunction •  Connector or terminal malfunction •  Short to power supply in the wiring harness…

P024A Persistent Air bypass valve governor deviation DETECTION CONDITION •  The PCM monitors the air bypass valve position using the air bypass valve position sensor. If the actual air bypass valve position offset difference with target value is more than threshold. The PCM determines that the air bypass valve governor deviation is below or above limit….

DTC P024B Air bypass valve stuck or jammed error DETECTION CONDITION •  The PCM monitors air bypass position using air bypass valve position sensor. If the air bypass valve position signal does not change while air bypass valve operating condition. The PCM determines that the air bypass valve is stuck. •  The PCM monitors air bypass position…

Since 1996, all automobiles and light duty trucks being sold in the US must come equipped with On Board Diagnostics Generation II Emissions Control Systems, hence the acronym OBD-II. OBD-II constantly monitors the performance of your Emissions Control System and will turn on your Check Engine Light whenever a malfunction occurs that causes the vehicle…

If your 1999-2010 Jeep Grand Cherokee’s ‘Check Engine’ light is on, you can check for Diagnostic Trouble Codes (DTCs) without having an OBD (On Board Diagnostics) II Code Scanner. All you need is your key. Here’s how to find the Diagnostics  Trouble codes (obd-ii): Steps Start with the key out of the ignition, all doors,…

What is Diagnostic Trouble Codes (OBD-II) for your Cars? Many vehicle owners know their cars come equipped with a computer, but very few know that every time something goes wrong in one of its many systems, the computer stores a code for it in memory. These are known as diagnostic trouble codes. Automobiles, at least…
