B00B1 Datsun Laurel Diagnostic Trouble Code
B00B1 Datsun Laurel code definition:
B00B1 is a kind of OBD-II Diagnostic B-Body Diagnostic Trouble Code for Datsun Laurel.
B00B1 Datsun Laurel is triggered when the bank 1 camshaft position sensor doesn't match the signal from the crankshaft position sensor. If the car doesn't start, they will proceed by testing the voltage at the fuel pump connector and see if the fuel pump relay, fuse, and PCM circuitry should be inspected.
Symptoms
Symptoms of a B00B1 Datsun Laurel diagnostic trouble code may include:
- Lack of power
- Faulty O2 Sensor
- Poor acceleration
- 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 :
- Defective ECU strategies or components will prevent proper regeneration
- The Mass Airflow sensor is a hot wire that senses the volume of air entering the intake manifold. The computer uses this information to control fuel mixture.
- Rough running engine due to misfiring plugs. Many engines have misfire codes to indicate the cylinder effected, such as P0307 for number 7.

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 :
Look for missing ground strap or a rusty ground where the fuel tank is grounded to the frame. Check for damage to the wiring harness connector.
It should be pretty close to battery voltage (12 volts). If not, then this is the circuit that has the problem.
