Guide To P07B4 OBD Error Code Solutions
OBD Code P07B4 - Transmission Park Position Sensor/Switch "A" Circuit High
The
trouble code P07B4 can be explicated as Transmission Park Position
Sensor/Switch "A" Circuit High. The main motive of the transmission
park position sensor/switch "A" circuit is to detect the overall
status of the transmission. ow when the
transmission would be placed into the park position, a signal would be sent to
the powertrain control module by this circuit. Depending upon a particular
vehicle, the circuit is generally a safety feature to prevent the starter from
engaging with the automatic transmission in gear.

Easy Diagnosis Of Engine Error OBD Code P07B4
If
you want to easily diagnose this trouble code, then you must follow the steps
which are mentioned here as below:
- The
constituents which are associated with the transmission park position
sensor/switch "A" circuit should be located.
- 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 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 P07B4 Code
- The
wiring might have some flaws
- Negligence in the powertrain control module
- Transmission park position sensor might start failing
