Error Code P07B6: What It Means & What To Do?

<<See All OBD Codes

The trouble code P07B6 can be explained as Transmission Park Position Sensor/Switch "A" Circuit Performance/High. The transmission park position sensor/switch circuit is monitored by the transmission control module. Now when the transmission park position sensor/switch would be out of the parameters set by the manufacturer, then the TCM would set this error code.

We believe that an investment in knowledge pays the best interest. So why not learn more about the P07B6 error code? This trouble code would start appearing when the powertrain control module would detect that there are some faults in the Transmission Park Position Sensor/Switch "A" Circuit.

You must know the codes which are generally related to the transmission park position sensor/switch "A" circuit malfunctions and they are P07B2, P07B3, P07B4, P07B5, P07B6, and P07B7. It is the PCM which would activate this error code. Due to this, the check engine light or the service engine soon light would start appearing.

What causes this problem with the Transmission Park Position Sensor/Switch "A" Circuit Performance/High?

• Quirks in the wiring
• The powertrain control module might be damaged
• The transmission park position sensor/switch might not be functioning properly
• Defective connector 

1. Oxygen Sensor - A faulty Oxygen Sensor can be troublesome. You can always rely on us as we have best auto parts for our customers.
2. Air Fuel Ratio Sensor - If everything is alright with Oxygen Sensor, then there is surely some defect in Air Fuel Ratio Sensor. Get it replaced before the situation gets worse.
3. EGR Valve Gasket - P07B6 code can display due to some faults in the EGR Valve Gasket. So, it is very important to replace the EGR Valve Gasket with us at equitable prices.
4. Manifold Absolute Pressure Sensor - Do you remember when was the last time you got your car Manifold Absolute Pressure Sensor checked up? A dirty Manifold Absolute Pressure Sensor can cause a lot of issues like displaying P07B6 code.
5. Crankshaft Position Sensor - There can be some issues with the Crankshaft Position Sensor due to which you may see P07B6 code appearing over and over again. Visit us to buy best quality Crankshaft Position Sensor online.
6. Idle Air Control Valve - Are you facing some faults in your Idle Air Control Valve? Don’t worry and get them replaced or else P07B6 code can turn up.
7. Engine Coolant Temperature Sensor - Common cause behind this P07B6 error code can be some fault in Engine Coolant Temperature Sensor. So, it will be a good decision to replace

Here are some steps which you should follow in order to diagnose this fault code:

• First of all, you must search all of the components associated with the transmission park position sensor/switch "A" circuit. This will include the transmission park position sensor/switch, wiring, connectors and the PCM on a simplex system. It all depends upon the specific year, make and model of the vehicle this circuit may incorporate more components.
• Now once you have located all these components, a thorough visual inspection should be conducted to check all of the associated wiring and connectors for obvious defects such as scraping, rubbing, bare wires or burn spots.
• The connectors should also be checked for corrosion build up or damaged pins. The advanced steps become very vehicle specific and require the appropriate advanced equipment to perform accurately. These procedures require a digital multimeter and the specific technical references for the vehicle. Voltage requirements will vary depending upon the specific year, make and model of the vehicle.
• The requirements of the voltage would differ depending upon the specific vehicle, the transmission park position sensor/switch circuit configuration and the components incorporated. Technical data should be referenced to obtain the correct voltage range for the transmission park position sensor/switch and the appropriate troubleshooting sequence to follow.
• The right voltage input to a sensor/switch with no voltage output generally indicates internal failure. If the absence of a power source or ground is identified, continuity testing may be needed to check the overall condition of the wiring and connectors.
• Continuity tests are always performed with the power removed from the circuit and the normal readings should be 0 ohms of resistance unless otherwise specified by the technical data. Resistance or no continuity indicates defective wiring or connectors that are shorted or open. Make sure that you repair them properly or get the replaced.

Common Mistakes When Diagnosing The P07B6 Code

• Non-observance of the powertrain control module
• Some issues related to the wiring
• Transmission park position sensor might start failing
