All of these concerns can be the result of an inappropriate Manual Lever Position (MLP) sensor signal. The MLP sensor consists of six resistors connected in series (ganged). The resistance of the MLP sensor will vary based on which range the transmission is in. The MLP circuit can be checked using the following steps. (Step 1) Check the MLPS ground: Turn the ignition on. The voltage on pin 46 (sensor ground ) should not exceed .1v. If the voltage is excessive, add an additional ground to the existing ground wire (figure 2). Figure 2 Splice an additional ground from the existing ground wire to a known good ground.The negative post of the battery is the best. This view is of the pins of the MLP connector pins. (Step 2) Check the MLPS voltage: The voltage at pin 30 should vary-in increments- according to the position of the manual lever (figure 3). MLP voltage (ignition on) should be within 20% of these specifications Note It is recommended that you use a break-out box. If a break-out box is not available, you will need to pierce the wires to pins 30 and 46 for these tests. (Step 3) Check the resistance of the MLPS: The resistance of the MLPS (pins 30 and 46) should change-in increments-with the position of the manual lever (figure 4). Note If this test is being done with a break-out box, disconnect the computer first (make sure the ignition is off). If this test is being done without a break-out box, disconnect the MLPS from the vehicle harness. REVISED This is a revised bulletin. Remove bulletin 230 from your files. Note Testing beyond this point will include tests of the harness. Consult the appropriate repair manual for this.

The throttle position (TP) sensor is a potentiometer that varies resistance according to changes in throttle plate position. The powertrain control module (PCM) measures the signal voltage from the TP sensor which is a reduced value of the PCM 5-volt reference. The voltage ranges from 0.4 (+/-0.2) volts at 0% throttle position to 4.7 volts at wide open throttle. DTC P0122 sets when the TP sensor signal voltage at the PCM is below the calibrated voltage value. DTC Parameters DTC P0122 will set if TP sensor voltage is less than 0.2 volts when: z The condition exists for longer than 10 seconds. z The ignition is ON. DTC P0122 diagnostic runs continuously with ignition ON. DTC P0122 is a type A DTC. Diagnostic Aids Important If DTC P1635 is set, diagnose that DTC first. 2002 Saturn SL
To locate an intermittent problem, use a scan tool to monitor TP SENSOR voltage with ignition ON, engine OFF. Wiggling the wires while watching for a change in TP SENSOR voltage may locate the area where an open or short to ground in the wiring could lie. An intermittent open in the TP SENSOR can cause this DTC to set. Use the scan tool to monitor TP SENSOR as the accelerator pedal is slowly depressed. The voltage should change smoothly from 0.4 volts at 0% throttle, to 4.7 volts at wide open throttle (+/-0.2 volts).
