SOURCE: no spark on a 1991 cadillac seville coil, ignition

You need to check for power with a test light to the distributor components.Check for power at bat terminal on distributor while cranking.. I would replace the module and coil, plenty of them at the salvage yard. Testing them is not always correct off the car by the zone.

How do I adjust the throttle position sensor on my 93 cadillac seville sls 4.9l engine?


4.5 And 4.9L Engines
  1. Remove the air cleaner.
  2. Remove the TP sensor connector.
  3. Unscrew the 2 TP sensor attaching screws and retainers, and remove the TP sensor.

To install:
  1. With the throttle valve in the normal closed idle position, install the TP sensor on the throttle body assembly.
  2. Install 2 TP sensor attaching screws with retainers. Do not tighten the screw until the TP sensor is adjusted.
  3. Install the TP Sensor connector. Adjust the TP Sensor and perform the idle learn procedure.
  4. To Perform the TP sensor adjustment.
    1. Disable the generator by grounding the green harness connector plug adjacent to the generator.
    2. Start the engine, enter diagnostics, and select PCM override PS103 'ISC Actuator'
    3. Press the 'COOLER' button on the CCP to retract the ISC Actuator. This action will disengage the A/C compressor and command the EGR 'OFF'. The Climate control center display will change from '50 to 00'. The ISC Actuator will slowly retract (about 20 seconds) to a fully retracted position. Verify that the throttle lever is resting on the minimum idle speed screw. With the ISC Actuator plunger fully retracted, disconnect the ISC harness.
    4. Select the PCM data PD01, 'TP Sensor', while still in PCM override PS03. Note the throttle position (in degrees) displayed on PCM parameter PD01.
    5. (-0.5° TO + 0.5°)

      No TP sensor adjustment required. Reattach the ISC Actuator harness and disconnect the grounding wire at the generator.
    6. TP Sensor (-10.0° TO -0.6°) or TP Sensor (+ 0.6° TO + 90.0°) TP Sensor adjustment required.

  5. With the engine 'OFF' and the ignition 'ON', reenter diagnostics and select PCM override PS03 'ISC Actuator'. Press the 'COOLER' button to retract the ISC Actuator the minimum air setting.
    1. Loosen the TP sensor screws just enough to permit the sensor to be rotated. Open the throttle slightly and allow the throttle lever to snap shut against the minimum air screw. Adjust the TP sensor so the parameter display is 0°. Tighten the TP sensor mounting screws with the sensor in the adjusted position. Recheck the parameter to be sure the TP sensor parameter is (-0.5° to + 0.5).
    2. Install the air cleaner.

Obd codes for a 1994 cadillac seville sls


It means the heater circuit for the O2 sensor has failed. An O2 sensor has to be up around 900 degrees to function properly, and if its heater fails, it won't get up to temperature (thus the "not ready" diagnosis). Replacing the O2 sensor will fix your problem.
