P007B - OBD Trouble Code

<<See All OBD Codes

Do you want to know the reason why P007B trouble code is triggering up again and again? The main reasons for this are that there is some sort of faults in the Charge-air Temperature Sensor, defective turbocharger or supercharger and there can also be some issues with the Powertrain Control Module. Take care of all these car parts or else your car may have to face some major issues.

Do you want to know something about P007B error code? Don’t worry as Parts Avatar Canada is here for your service. An intercooler is also known as a charge air cooler and it is generally found in turbocharged or supercharged vehicles. It is because of high pressure that the air which is compressed by the turbocharger becomes extremely hot. Now the hot air would start entering the charge air cooler where it cools down. That cool air would then start entering the engine.

What causes this problem with the Charge Air Cooler Temperature Sensor Circuit Range/Performance Bank 1?

• Defective Charge-air Temperature Sensor
• Charge-air Temperature Sensor harness may be opened or shorted
• Bad electrical connection with the Charge-air Temperature Sensor circuit
• Faults in the sensor
• Problems with the wiring
• The charge air cooler may be failed or restricted
• Faulty Powertrain Control Module

1. Engine Control Module - Are there some faults in your Engine control module? Don’t waste time and get them replaced or else P007B code can turn up.
2. Air Cooler Assembly - Common cause behind this P007B error code can be some fault in Air cooler assembly. So, it will be a good decision to replace them now.
3. Turbocharger - P007B code does not really end up spoiling your engine control module, but it might also accompany few Turbocharger issues. We have best powertrain related parts with us.
4. Supercharger - There can be some issues with the Supercharger due to which you may see P007B code appearing over and over again. Visit us to buy best quality Supercharger online.
5. Temperature Sensor - Are you facing OBD Error Code P007B? Don’t worry as you can fix this issue with new Temperature Sensor. We care for our customer, that’s why we have Temperature Sensor for every make and model.
6. Air Cooler Sensor - A broken Air Cooler Sensor can cause a lot of issues. It would be nice if you get it replaced on time.

Willing to know some common symptoms of OBD Trouble Code P007B? Your wish is our demand. Have a look at them below:

Common Symptoms

• Check engine light may start illuminating
• Vehicle will start running in limp mode to protect the car engine
• The overall engine power would be reduced
• Reduction in the fuel economy

Learn the ways with which you can correct this trouble code:

• You must inspect the reference voltage side of the circuit. You must use a digital Multimeter set to volts to check for a 5-volt reference from the PCM at one of the two charge air cooler temperature sensor terminals. If there is no reference signal, then just connect the meter set to ohms (make sure that the ignition off) between the reference voltage pin on the CACT and the reference voltage pin on the PCM. There is an open circuit between the PCM and the sensor if the meter reads out of limits the it should be located and repaired properly. If a numeric value is read by the meter, then there is continuity
• If everything is good up to this point, you'll want to check that there is 5-volts coming out of the PCM at the reference voltage terminal. If there is not a 5-volt reference from the PCM, the PCM is probably faulty
• The next step is to inspect the ground side of the circuit. Just connect the meter set to ohms between the ground terminal on the charge air cooler temperature sensor and the ground terminal on the PCM. If by any chance the meter reads out of limits (OL), then there is surely an open circuit between the PCM and sensor. This must be located and repaired. There is continuity if any numeric value is read by the meter. Finally, you have to check that the PCM has a good ground. You can do this by attaching one-meter lead to the PCM ground terminal and the other one to chassis ground. Now again if the results of the meter are out of limits, then there is surely an open circuit between the PCM and the ground that should be carefully located and then repaired

Don’t get tensed if you are still facing any of these issues as we care for our customers and that’s why we offer a good range of Powertrain Control Module, Timing Belt, Throttle Position Sensor and a lot more. We are sure that now all your issues would be resolved.

The best thing would be to visually inspect the charge air cooler temperature sensor as well as the wiring. There can be some loose connections and damaged wiring which should be looked upon. You can also inspect the charge air cooler and ducting. If damage is found, repair as necessary, clear the code and see if it returns.

• You can always do some preliminary circuit testing. You can always use a scan tool which would help you to monitor the charge air coolant temperature sensor data parameter. Then you can disconnect the CACT sensor. Due to this the value of scan tool should drop to a very low value. The next step is to connect a jumper wire across the terminals. If a very high temperature is displayed by the can tools, then the connections are sound and the ECM can recognize the input. This would mean that the issue is with sensor and it is not a circuit and a PCM related issue.
• The next step is to test the sensor. You must disconnect the charge air cooler temperature sensor connector. Then the resistance between the two sensor terminals should be measured with the help of a digital Multimeter. Set it to ohms. Start your car engine and watch the value of the meter. With the warming up of the engine, the values would start decreasing smoothly. If the overall engine temperature rises, but at the same time CACT resistance does not decrease, then the sensor would be defected and it should be immediately replaced.

Common Mistakes When Diagnosing The P007B Code

• The air temperature failure should be charged
• Failure with the Powertrain Control Module
• Some issues with the wiring
