P07B9 - OBD Trouble Code

<<See All OBD Codes

The trouble code P07B9 can be explicated as Transmission Park Position Sensor/Switch "B" Circuit Low. It is the Transmission Control Module which carefully detects the Transmission Park Position Sensor/Switch circuit. The TCM would set up the P07B9 fault code when the Transmission Park Position Sensor/Switch would be out of the parameters which have been set by the manufacturer.

Do you want to gain some more knowledge about the P07B9 trouble code?

There are lot of friction elements required when a mechanical operation of an automatic transmission is being considered. The same friction materials like the clutch as used by the manual transmissions.

Here we are referring to the automatic transmission. One thing which you must keep in mind that its symptoms as well as causes would surely vary as it depends upon a number of things. Just keep in mind that the initial thing which should be considered is the general health of the automatic transmission as well as automatic transmission fluid.

What causes this problem with the Transmission Park Position Sensor/Switch "B" Circuit Low?

• ATF might be little
• Tattered friction element
• There can be some issues related to the wiring
• Bumpy tire sizes
• The rotational speed/circumference may be unequal
• Defective transmission control module
• Unsound engine control module
• There can be water damage to module and harness

Have a look at some steps which you should follow in order to diagnose this fault code:

Just make sure that you have carefully pinpointed all of the components which are associated with the transmission park position sensor/switch "B" 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. After these components are located, then you should perform a visual inspection properly to inspect all of the associated wiring as well as connectors for obvious faults like 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.
