Kia 2002 Saturn SL will set if TP sensor voltage is less than 0.2 volts

download
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).

connected to the vehicle, the TBC module will enter a “sleep mode” but still continue to send a PWM voltage signal to the trailer tow connector every 4 seconds to detect when a trailer is connected. When the ignition key is in the RUN position and the module is in sleep mode, pressing a gain button or sliding the manual switch will cause the module to “wake up”. If a trailer is not connected to the vehicle, the display should prove out for 3 seconds, then the trailer icon should illuminate red and the IC message center should display TRAILER DISCONNECTED or CHECK TRAILER. If a trailer is connected to the vehicle, the display should prove out for 3 seconds and then the trailer icon should illuminate green. Inspection and Verification NOTE: A trailer brake emulator tool is available to verify that the TBC module and vehicle wiring are functioning correctly. 1. Verify the TBC system is correctly installed by checking that the vehicle is equipped with a brake pressure transducer on the master cylinder. If the brake pressure transducer is not present, then the TBC system has been erroneously installed. 2. Verify the customer concern. 3. NOTE: The TBC does not function with electric-over-hydraulic or surge trailer brake types. Verify that the trailer brakes are electric-actuated drum type brakes. 4. Verify the stoplamps operate correctly by applying and releasing the brake pedal with the ignition switch in the OFF position and the trailer disconnected. If the stoplamps do not operate correctly, refer to Section 417-01 . If the stoplamps operate correctly, proceed to the next step. 5. Visually inspect for obvious signs of mechanical or electrical damage. Visual Inspection Chart 6. If the cause is not visually evident, connect the scan tool to the data link connector (DLC) and select the vehicle to be tested from the scan tool menu. If the scan tool does not communicate with the vehicle: * check that the program card is correctly installed. * check the connections to the vehicle. * check the ignition switch position. 7. If the scan tool still does not communicate with the vehicle, refer to the scan tool operating manual. 8. Carry out the scan tool data link test. If the scan tool responds with: * CAN, ISO, or UBP circuit fault; all electronic control units no response/not equipped, refer to Section 418-00 . * No response/not equipped for the TBC, GO to Pinpoint Test A . * System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, and carry out self-test diagnostics for the TBC and the antilock brake system (ABS) module. 9. If the DTCs retrieved are related to the concern, go to the Trailer Brake Control (TBC) module Diagnostic Trouble Code (DTC) Chart or Anti-Lock Brake System (ABS) Module Diagnostic Trouble Code (DTC) Chart to continue diagnosis. 10. If no DTCs related to the concern are retrieved, GO to Symptom Chart to continue diagnosis. NOTE: Always retrieve the continuous DTCs after running the self-test.
