P101B Lada Priora code definition:
P101B is a kind of OBD-II Diagnostic P-Powertrain Diagnostic Trouble Code for Lada Priora.
P101B Lada Priora is described as Intake Air Temperature (IAT) Circuit Malfunction. It's actually a general trouble code for a problem on IAT electrical circuit sensor, as it sends incorrect voltage input signals to the PCM. Other serious codes may cause this code to pop up, and they may come with dangerous drivability issues that may expose you to safety risks and cause damage to the engine in the long run.
Symptoms
Symptoms of a P101B Lada Priora diagnostic trouble code may include:
- Malfunction Indicator Lamp (MIL) illuminated
- Carbon Buildup on O2 Sensor
- Poor fuel economy
- 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

Possible Causes :
- A large vacuum leak would cause a massive amount of un-metered air to enter the intake manifold resulting in an overly lean mixture.
- Faulty IMRC actuator/sensor
- Low fuel pressure caused by a clogged filter, failing fuel pump, failed fuel pressure regulator or clogged or leaking injectors.

Common Misdiagnoses
- Exhaust Gas Recirculation System Valve 1 Problem
- BBV Sensor Circuit Low Voltage Problem
- Transmission Engaged At High Throttle Angle Problem
- Cruise Inhibit Control Circuit Problem
- TFP Valve Position Switch-Drive Without Drive Ratio Problem
Repair Processes :
Now, clear the codes and test-drive the vehicle to see if the code is reset.
Find out what kind of system you have and verify that voltage to the fuel level sensor is present at the fuel pump wiring harness.
Process Tips
Diagnostic trouble code P101B Lada Priora 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.
