Code p0705 All circuits from the range sensor out have good continuity with no shorts to power or ground OR each other. Have replaced the range sensor/PRNDL, the ECU and the instrument cluster... P0705 returns after about 3 miles of driving. What next ??

sensor that was replaced per the code scanner , That's where you made your mistake . No code tell's you to replace a part without testing . Did you do factory trouble shooting per code diagnostic testing procedures ?
The inflatable restraint front end sensor utilizes a unidirectional 2-wire circuit. The front end sensor modulates current on the interface to send ID, state of health, and deployment commands to the inflatable restraint sensing and diagnostic module (SDM). The SDM serves as a power source and a ground for the front end sensor. When the ignition is turned ON and input power from the SDM is first detected, the front end sensor responds by performing internal diagnostics and sending an ID to the SDM. The SDM considers the ID to be valid if the response time is less than 5 seconds. The front end sensor continually communicates status messages to the SDM, which determines if a fault is present in the front end sensor circuit. When a fault is detected, the SDM may reset the front end sensor up to 2 times by removing and reapplying power to it. If the fault is still present, the SDM will set a DTC.

B0091 00
• The front end sensor has been shorted to voltage, open, or shorted to ground.
• The front end sensor current has been above 23 mA for longer than 5 milliseconds.
• The SDM has not received a message from the front end sensor for more than 375 milliseconds.

Circuit/System Testing
Important: When removing the connectors, inspect for damage or corrosion. Damage or corrosion to the following requires repair or replacement of the affected component/connector:
• Front end sensor
• SDM module
• Front end sensor wiring harness connector
• SDM wiring harness connector
Ignition OFF, disconnect the harness connector at the front end sensor and the SDM.
Ignition ON, test for less than 1 volt between the front end sensor signal circuit terminal 2 and ground.
? If greater than the specified range, test the signal circuit for a short to voltage.
Ignition ON, test for less than 1 volt between the front end sensor low reference circuit terminal 1 and ground.
? If greater than the specified range, test the low reference circuit for a short to voltage.
Test for infinite resistance between the front end sensor signal circuit terminal 2 and ground.
? If less than the specified value, test the signal circuit for a short to ground.
Test for infinite resistance between the front end sensor low reference circuit terminal 1 and ground.
? If less than the specified value, test the low reference circuit for a short to ground.
Test for less than 1 ohm between the SDM signal circuit terminal 38 and the front end sensor circuit terminal 2 harness connector.
? If greater than the specified range, test the signal circuit for an open/high resistance.
Test for less than 1 ohm between the SDM low reference circuit terminal 36 and the front end sensor circuit terminal 1 harness connector.
? If greater than the specified range, test the low reference circuit for an open/high resistance.
If all circuits test normal, test or replace the front end sensor.
Reconnect all SIR components. Ignition ON, verify the DTC is not set as current.
? If the DTC resets as current, replace the SDM.

The transaxle control module (TCM) primarily controls shift points and lockup engagement.
The transaxle is controlled by an electronic shift system. The TCM processes input signals. From the information received, the TCM controls the transaxle hydraulic system.
The electronic shift system consists of the following components:
• TCM
• Shift Solenoid (SS1 and SS2)
• Pressure Control Solenoid (PSC)
• Lockup Solenoid
• Input Shaft Speed (ISS) Sensor
• Output Shaft Speed (OSS) Sensor
• Transmission Fluid Temperature (TFT) Sensor
• Park/Neutral Position (PNP) Switch

Have the vehicle checked for DTC'S - diagnostic trouble codes
When the TCM detects an invalid combination of TR switch signals, then DTC P0705 sets. DTC P0705 is a type A DTC.

The transmission range (TR) switch is part of the park/neutral position and back-up lamp switch assembly and is mounted on the transmission manual shaft. The TR switch is a multi-signal switch. The transmission control module (TCM) supplies voltage to the TR switch. Each gear selector lever position grounds one or more of the signal circuits in a unique pattern. In order to determine the gear range selected by the driver, the TCM compares the voltage combination on the signal circuits to a TR switch combination table stored in memory. Refer to Transmission Range Switch Logic .

DTC P0705
Transmission Range (TR) Switch Circuit

The transmission range (TR) switch is part of the park/neutral position and back-up lamp switch assembly and is externally mounted on the transmission manual shaft. The TR switch is a multi-signal switch. The PCM supplies ignition voltage to the TR switch on four signal circuits (A, B, C, and P). Each gear selector lever position grounds one or more of the switch circuits. In order to determine the gear range selected by the driver, the PCM compares the voltage combinations on the signal circuits to a look up table stored in the PCM memory. PCM detects the selected gear range by the state change of the switch input. Refer to Transmission Range Switch Logic table.
Switch input to the PCM is represented on the scan tool as HI and LOW. HI indicates an ignition voltage signal. LOW indicates a zero voltage signal. The four parameters represent transmission range switch signal A, B, C and Parity.
When the PCM detects an invalid TR switch signal combination, then DTC P0705 sets. DTC P0705 is a type C DTC.

From reading your post an my years of experince your best bet would be to take to a qualified repair shop . You do not have the knowlede or tool's to fix these problems .

Install a Scan Tool .
Turn ON the ignition, with the engine OFF.
Select TR Sw. on the Scan Tool .
With the Scan Tool , observe the TR Sw. display while selecting each transmission range: P, R, N, D3, D2 and D1.
Does each selected transmission range match the Scan Tool TR Sw. display?

P0700

The transmission of a vehicle which has suffered a transmission problem will send the P0700 code to the vehicle engine control module (ECM)

P0705 Transmission Range Sensor Circuit Malfunction

Possible causes

- Open or short park/neutral position switch circuit
- Poor park/neutral position switch circuit connection
- Misadjusted park/neutral position switch
- Park/neutral position switch may be faulty

P0455. A code p0455 most likely means one or more of the following has happened:

A loose or improperly affixed gas cap

A non-conforming gas cap (i.e. not factory/original brand)

Other leak or damaged piece in EVAP system

Transmission Range Sensor "A" Circuit (PRNDL Input)

HI. Lets start with the P0133 Code:

This code is in reference to the O2 sensor that is behind the catalytic converter(down stream sensor). You will need to test the connecting harness that links that sensor to the ECM for shorts. If the harness is ok, simply, replace that sensor.I would also advise to check for any apparent exhaust leaks as well and for proper MAF functions. You will more than likely have to replace the sensor, but ti be safe, check the areas I have stated first before you replace it.

Now, lets move on to the next code. This will be the P0705:

This code is in reference to the park/neutral position switch circuit. The only recourse here will be to replace that switch. It has failed.

DTC P0708 - Transmission Range Sensor Circuit High Input

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...

DTC P0706
The PCM determines which gear is selected by a combination of opens and grounds in circuits 771, 772, and 773 at the transaxle park/neutral
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 ignition cycle.

The difference between DTC P0706 and DTC P0705 is that a possible bit pattern error due to misadjustment could set a DTC P0706.

Test Description
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 shift positions.
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 that voltage.
6. DTC P0706 may have been set due to 1 of the circuits being shorted
to voltage. This step verifies if a short to voltage exists.

Repair Verification
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.

Diagnostic Aids
When the PCM detects a fault in the circuit, an open, ground, or short,
the PCM will open the circuit internally to protect the circuit.

If no circuit problems can be detected, check the shift cable and switch
adjustment.

Important
Refer to the chart from DTC P0705.

This DTC will cause the transaxle to start out in 2nd gear.

Hope helps (remember rated this).

Yup, if you scanned your engine computer and you got a code P0705, you can bet that's why your Check Engine light is on.

P0705, however, is NOT a Vehicle Speed Sensor code on this vehicle. It is a Digital Transmission Range Sensor code. It is caused by an open or shorted circuit in the TR-1, TR-2, TR-3a or TR-4 circuits. This code CANNOT be set by an incorrectly adjusted TR Sensor.
