The major symptom of this code is that, emission coming from the vehicle could increase due to the CTS taking longer to reach its operating temperature. This increase in emissions is what causes the Check Engine Light to come on so that the vehicle can be repaired as soon as possible.

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

ECT sensor design usually consists of a thermal resistor that is dipped in a hard resin and sealed in a metal or plastic housing. Brass is the most popular of these housing materials because of its durability. In most cases, the ECT sensor is threaded so that it may be screwed into a coolant passage in the engine intake manifold, cylinder head, or block. The level of thermal resistance in the ECT sensor decreases as coolant warms and flows across it. This leads to increased ECT sensor circuit voltage at the PCM. As the engine cools, sensor resistance increases and ECT sensor circuit voltage (to the PCM) is reduced as a result.

The PCM recognizes these fluctuations in voltage as changes in engine coolant temperature. Fuel delivery and ignition timing strategy are among the functions affected by actual engine coolant temperature and input data from the ECT sensor. The radiator coolant temperature sensor monitors coolant temperature in much the same manner as the ECT sensor. It is typically inserted into one of the radiator tanks but may also be fitted into a pressurized coolant reservoir.

If the PCM detects voltage signals from the ECT sensor and the radiator coolant temperature sensor which differ from one another by greater than the maximum allowable parameter, a code P00B6 will be stored and a malfunction indicator lamp (MIL) may be illuminated. Multiple drive cycles with a failure may be required for MIL illumination.

What causes the problem with the Radiator Coolant Temperature/Engine Coolant Temperature Correlation?

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

1. Turbocharger - Change your old turbochargers as they might not be pushing enough air into the engine.
2. Supercharger - Replace damaged supercharger and parts today as there might be inconsistency in the air pressure and the air density, thus impacting engine output.
3. Turbo Boost Sensor - Boost pressure sensors affect the air pressure delivered to the mechanical wastegate actuator. Replace old/damaged sensor today!
4. Intake Manifolds - Replace damaged or old air intake manifolds as it adversely affects the engine’s performance. Visit us today!
5. Boost Pressure Gauge - Change faulty gauge from us and get the correct pressure readings.
6. Turbocharger Wastegate - Damaged wastegate should be immediately replaced to solve the problem of low engine power. Buy now!
7. Engine Control Module - OBD Error Code P00B6 can also be due to faulty ECMs. Check and replace the faulty components now!
8. Powertrain Control Module - P00B6 error code also relates to problems with the PCM which might need reprogramming or replacement. Find all the Powertrain related parts with us.
9. Auto Switches & Sensors - Check for defective switches or faulty sensors first in the diagnosis process. So, it will be a good decision to replace them now.
10. Diagnostic Tool - In order to detect the error, always make use of professional diagnostic tools. Visit us today for all types of tools and equipment’s.

This code would be considered a moderately severe issue. This will vary on what symptoms you have and how the fault is actually affecting your vehicle’s performance. The fact that the CTS's functionality directly influences the engine's air/fuel mixture, makes this an issue you do not want to leave unattended. Neglect this problem long enough, and you could be faced with some hefty engine repair bills.

Common Symptoms

• Erratic idle and hard cold start
• Engine stalling and not starting
• Increased fuel consumption
• Smoke coming out of exhaust
• Fuel leakage smell
• Incorrect temperature readings
• Declined engine performance and acceleration

Common Mistakes When Diagnosing OBD Code P00B6

The most common mistake is to simply replacing the CTS without performing and diagnostics at all. This happens a lot because the vast majority of the time it is the sensor itself that has failed, as it undergoes a lot of stress and is a high failure item so it can be easy to get lazy and just replace the sensor. Measuring the wrong terminals in the connectors is also a major mistake. It is important to know how to read the wiring diagrams so you know you are measuring the correct circuits and follow the diagnose procedure.
