B0101 Adler 10 Diagnostic Trouble Code
B0101 Adler 10 code definition:
B0101 is a kind of OBD-II Diagnostic B-Body Diagnostic Trouble Code for Adler 10.
B0101 Adler 10 is described as Oxygen Sensor Circuit No Activity Detected (Bank 1, Sensor 1). This means there's a problem in the front oxygen sensor on Bank 1, as the O2 sensor is inactive. The PCM then uses this data to provide the right strategies for the fuel delivery and ignition timing of the engine.
Symptoms
Symptoms of a B0101 Adler 10 diagnostic trouble code may include:
- Faulty or damaged wiring
- The engine oil will exhibit dilution from the ECUs attempts to increase engine temperature. Some vehicles advance the fuel injection timing slightly after top center to afterburn a small amount of fuel to increase exhaust temperatures. Some of this fuel enters the crankcase. When the ECU determines the necessity to regenerate the DPF, the service life of the oil be shortened significantly
- Poor fuel economy
- The light may stay on or light intermittently as the DPF regenerates. The engine will be sluggish on acceleration.
|
Possible Causes :
- An air leak forward of the DPF will change the sensor readings resulting in the code
- Rusty exhaust systems, cracked exhaust manifolds or damaged or missing gaskets or donuts will cause air leaks.
- A large vacuum leak would cause a massive amount of un-metered air to enter the intake manifold resulting in an overly lean mixture.

Common Misdiagnoses
- Vehicle Speed Output Circuit Problem
- Cruise Control Servo Indicates Low Problem
- A/C System High Pressure High Temperature Problem
- PCM Stack Overrun Problem
- Transmission Control Module Reprogrammable Memory Problem
Repair Processes :
If you find a related TSB, the information will often help in diagnosing the code in question as TSBs are crested from many thousands of repairs.
With the valve disconnected, the red voltmeter lead should be attached to the IMRC valve power wire and the black voltmeter lead connected to ground.
Oxygen sensors signal the engine management computer the amount of oxygen present in the exhaust, which is used in determining and controlling the fuel ratio.
Process Tips
Diagnostic trouble code B0101 Adler 10 is not difficult to diagnose and repair. Thus, it always pays to have a qualified technician to look after your vehicle should this error code arise.
Diagnosing this code requires the engine to be in good running shape, without unmetered air entering the engine. If other codes that relates to misfiring condition, lean running or air entering the engine is present, then you must first fix those error codes before B0101 Adler 10.
Fortunately, B0101 Adler 10 is a fairly common OBD code, meaning that it applies to all makes and models of vehicles made after 1996.
