Error Code P07B2: What It Means & What To Do?

<<See All OBD Codes

The trouble code P07B2 can be described as Transmission Park Position Sensor/Switch "A" Circuit Open. This code is a powertrain diagnostic trouble code. It would apply to the OBD-II vehicles which have a transmission park position switch/sensor. They include but at the same time are not restricted to the automobiles from Dodge, Ford, Toyota, Land Rover, VW, Chevrolet, etc. Their steps for repairing would vary as it all depends upon the year, make, model and powertrain configuration. The fault code P07B2 is one of several possible codes associated to the Transmission Park Position Sensor/Switch "A" Circuit.

Don’t worry if P07B2 error code is triggering again and again. We offer wide range of auto parts at affordable prices to our dear customers. 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.

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

• Malfunctioning wiring
• Faulty transmission park position sensor/switch
• Issue of corroded or damaged connector
• There can be inoperative powertrain control module

1. Crankshaft Position Sensor - Do you remember when was the last time you got your car Crankshaft Position Sensor checked up? A dirty Crankshaft Position Sensor can cause a lot of issues like displaying P07B2 code.
2. Oxygen Sensor - Poor Oxygen Sensor can cause a lot of difficulties, so why not get it replaced at time?
3. Engine Coolant Temperature Sensor - Are there some faults in your Engine Coolant Temperature Sensor? Don’t waste time and get them replaced or else P07B2 code can turn up.
4. Air Fuel Ratio Sensor - OBD Code P07B2 can appear because of faulty Air Fuel Ratio Sensor.
5. Manifold Absolute Pressure Sensor - Everything is fine with Engine Coolant Temperature Sensor and still P07B2 code triggering? Then you must get your Manifold Absolute Pressure Sensor checked.
6. EGR Valve Gasket - There can be some issues with the EGR Valve Gasket due to which you may see P07B2 code appearing over and over again. Visit us to buy best quality EGR Valve Gasket online.
7. Idle Air Control Valve - A lot of issues can arise do to defective Idle Air Control Valve. Did you just see P07B2 code flashing? Now you know the reason why it is appearing. Get it inspected and replaced on time.

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P07B2 code by mentioning some major symptoms below:

Common Symptoms

• Starter might attract with the vehicle in gear
• The service engine soon light can start lighting up
• Issue of transmission not shifting into park
• There can be some issues in starting the vehicle
• Check engine light might come into signal
• Transmission might not move out of park

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P07B2:

• Make sure to mend the clogged EGR valves and/or tubes
• The leakage in the vacuum should be repaired
• You must fix the defective powertrain control module
• Repair or replace the quirky head gaskets
• Replace or repair the leaking internal engine components
• It is essential to restore the flawed camshaft sensor
• You must fix the defective catalytic converter
• Repair or replace the throttle position sensor
• Repair or replace the quirky oxygen sensor
• Make sure to mend the faulty spark plugs
• Diagnose the then carefully repair the other related trouble codes
• It is essential to restore the flawed distributor cap and rotor button, as well as wires, coils, and plugs
• Rehabilitate the defaults in the mass air flow sensor
• The malfunctioning crankshaft sensor should be repaired or replaced as per the need
• Carefully adjust the faults in the inoperative spark plug wires and/or coils
• Rehabilitate the defaults in the fuel injectors

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

• The constituents which are related with the transmission park position sensor/switch "A" circuit should first of all be located properly. 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. After these components are located, 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 need the appropriate advanced equipment to perform in the right way. There would a need of a digital multimeter and the specific technical references to carry out this procedure. 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 P07B2 Code

• Failure in the powertrain control module
• Non-performance of the transmission park position sensor
• Some issues related to the wiring
