OBD II Fault Code

  • OBD II P0706
Fault Code Definition
  • Transmission Range Sensor Circuit Range/Performance
The purpose of the automatic transmission is to match the engine's optimum power and torque characteristics to the driver's desired rate of acceleration and speed by auto-selecting different gear ratios or 'speeds' to power the wheels. The Transmission Range Sensor (also referred to as the PRNDL input and/or neutral safety switch) tells the transmission control module (TCM) and the powertrain control module (PCM) that the transmission is in park, reverse, neutral, drive, low, 2nd, 3rd etc. It is attached directly to the manual valve of transmission, so when the shift lever is moved say from park to drive, the Transmission Range Sensor communicates this critical information to the above mentioned vehicle computer systems.

P0700
Many vehicles have a control module for the automatic transmission called a transmission control module (TCM). The engine control module (ECM) communicates with the TCM to monitor the automatic transmission for faults. If the TCM detects a fault in the automatic transmission and sets a transmission related fault code, the ECM is informed of this also and sets a P0700 in the ECM memory.

700 is generic code meaning a transmission malfunction. It could electrical or mechanical. You'll have to retrieve the other codes. The solenoid packs are the most common parts replaced on these.

What is code po700


It means there is at least one transmission code set in the TCM's memory. P0700 is an informational code only. More diagnosis is necessary to identify what the transmission fault is. This requires a scan tool that will communicate with the transmission module

How to fix diagnostic codes po700 and po730 ?


Symptoms of a P0700 DTC may include:
  • Malfunction Indicator Lamp (MIL) illumination
  • The transmission may exhibit drivability problems like slipping, etc
More often then not, the cause of this code is that there is a transmission problem of some kind. The TCM detected the problem and set a code. P0700/PO700 means that a fault code is stored in the TCM. However this doesn't rule out the possibility of a failed PCM or TCM (unlikely).
For a P0700/PO730 the only real solution is to acquire a scan tool that will communicate with the transmission control module. Extracting this code from the TCM will be the first step in repairing the fault in the transmission.
If the TCM compatible scan tool will not communicate with the Transmission Control Module then that is a good indication that there may be a fault with the TCM itself.

1997 getting code P1776 & PO700 What does this mean


The code 700 is a notice that there is a problem with the trans control module, and code 1776 could be a problem with the low-reverse solenoid inside the trans. Code 1776 can trigger the code 700.
The solenoid would need to be tested.

Car wont shift from 2nd gear and speedometer doesnt work. diagnostic code p0700. what does this mean?


the PO700 code is a generic transmission code. You would need access to a proper scan tool to check for transmission codes. However if you speedo isnt working, it sounds as though you have a bad output speed sensor. This part runs about 60.00 from the dealer, and is fairly easy to install. No speed signal will put the transmission into limp mode, and keep it stuck in 2nd gear.
