P00B1 OBD Error Code: Problem & Solutions

<<See All OBD Codes

Is your engine stalling and facing problems when cold starting? Are you experiencing decreased fuel economy as well as low power from the car engines? All these must be the indication of OBC Code P00B1 error.

OBD-II Code Cooling fans may stay on all the time is defined as a Radiator Coolant Temperature Sensor Circuit

The CTS (Coolant Temperature Sensor) monitors the temperature of the vehicle’s coolant and sends the signal to the PCM (Powertrain Control Module).  Based on the temperature readings from the CTS (Coolant Temperature Sensor) the PCM (Powertrain Control Module) adjusts the air/fuel mixture accordingly.  When the PCM (Powertrain Control Module) reads that the signals from the CTS (Coolant Temperature Sensor) are out of vehicle specifications a trouble code will set.

What causes the problem with the Radiator Coolant Temperature Sensor Circuit?

• Faulty CTS (Coolant Temperature Sensor)
• Dirty or blocked CTS (Coolant Temperature Sensor)
• Faulty radiator
• Seal around CTS (Coolant Temperature Sensor)
• Damaged wiring/connections in the CTS (Coolant Temperature Sensor) circuit
• Faulty PCM (Powertrain Control Module)
• Bad fuse in the CTS (Coolant Temperature Sensor) circuit

1. Turbocharger - This component plays a very important role in the engine performance and thus need immediate replacement, if found faulty.
2. Supercharger - Supercharger affect the density of air the engine to make optimal air to fuel ratio. Thus, replace damaged supercharger and parts today!
3. Turbo Boost Sensor - Boost pressure sensors affect the air pressure delivered to the pneumatic and mechanical wastegate actuator. Replace old sensor today!
4. Boost Pressure Gauge - Replace faulty gauge from us and get the correct pressure readings.
5. Engine Control Module - Check for faults in the ECM and replace the damaged components to see if the error flashed back.
6. Powertrain Control Module - P00B1 error code also relates to problems with the powertrain. Find all the Powertrain related parts with us.
7. Auto Switches & Sensors - Common causes behind that P00B1 error code can be defective switches or faulty sensors. So, it will be a good decision to replace them now.
8. Intake Manifolds - Replace damaged or old air intake manifolds as it adversely affects the engine’s performance as well as the internal combustion process. Buy now!

Some of the most common indicators to the problem related OBD code P00B1 are as follows.

Common Symptoms

• Check Engine Light will illuminate
• The vehicle will be difficult to start
• Engine may stall
• Poor fuel mileage
• The engine will lack performance
• Smoke coming from the exhaust

At Parts Avatar Canada you can find quality replacement and performance parts that are needed to correct the problem related to code P00B1.

Some of the key components that can be replaced if found problematic are as follows.

• CTS (Coolant Temperature Sensor)
• Radiator

Common mistakes when diagnosing the P00B1 code

Some of the common mistakes done while changing diagnosing the OBD code P00B1 are:

• Improper assessment of the radiator temperature sensor failure
• Simply replacing the Powertrain Control Module (PCM) without considering other possibilities of problem
• Not noticing the damaged or loosened wiring and circuit problems
