My service engine light is on got it checked it has a p0706 code which is the Transmission Range Sensor Circuit Range/Performance?where do i find the part?
DTC P0708 - Transmission Range Sensor Circuit High
Check your transmission range sensor. There is a connector located where the cable
attaches to the tranny on the back (firewall side). Be sure its
connected and seated properly.
From what I understand the "range sensor" is basically the Input Turbine
Speed Sensor. Be sure the connector for this is also clean. This code is also set by the Nuetral Safety switch. Check the switch
with a multi meter to be sure its working properly.
Also, check your Engine Coolant Temperature Sensor. This sensor is used by
the PCM to help control tranny operations.
Also, can check this additional information for 1998 Saturn SL1...
The PCM determines which gear is selected by a combination
of opens and grounds in circuits 771, 772, and 773 at the transaxle
position switch. Each combination indicates a specific
selection on the
manual shift quadrant, P, R, N, D, 2, or 3.
Circuit 776 is either open
or grounded to produce an even number of
grounded circuits, 771, 772,
773, and 776. Invalid data indicates
that the sum of the grounded
circuits 771, 772, 773, and 776, in 1
of the manual shift quadrants is
equal to an odd number.
Conditions for Setting the DTC
DTC P0706 is set when the PCM has
detected an invalid bit pattern for
more than 3.5 seconds, twice per
The difference between DTC P0706 and DTC P0705
is that a possible bit pattern error due to misadjustment could set a
1. This step verifies the
conditions for DTC P0706 still exist.
2. If the shift cable or
switch is misadjusted, a DTC P0706 may set
while in certain gear
3. DTC P0706 may set due to 1 or more circuits
being shorted to
ground. By disconnecting the switch, the PCM should
read all circuits as high and the scan tool should display OPEN.
4. This step will isolate an open circuit. As each individual circuit
is grounded, the PCM/TCM should see the low signal and the tool should display INVALID.
5. The PCM/TCM supplies a 12 volt signal to each
transaxle park/neutral position switch circuit. This step tests for
6. DTC P0706 may have been set due to 1 of the
circuits being shorted
to voltage. This step verifies if a short to
Monitor DTC menu Code
Status for Pass Since Code Clear and Pass This Ignition Cycle. When
both have passed, the repair is verified.
Criteria for pass:
* No active DTC set.
* Two valid selector positions are decoded.
You must move the
shifter to obtain a pass.
the PCM detects a fault in the circuit, an open, ground, or short,
the PCM will open the circuit internally to protect the circuit.
no circuit problems can be detected, check the shift cable and switch
Refer to the chart from DTC P0705.
DTC will cause the transaxle to start out in 2nd gear.
Hope helps (remember rated this).
