DTC P0106 (P_R): Pressure Sensor Circuit Range/Performance Problem

  1. If DTC P0107 , P0108, P1102 or P1122 exist, diagnose and repair that DTC(s). DO NOT  diagnose DTC P0106.
  2. Turn ignition off. Connect and turn on SSM. Start engine. SSM function modes F20 and F21 checks signal value sent from the pressure sensor. Select SSM function mode F21. If displayed value is more than 85 kPa, go to step 4). If displayed value is less than 85 kPa, go to next step.
  3. Select SSM function mode F20. If displayed value is less than 32 kPa, go to step 5). If displayed value is more than 133 kPa, replace pressure sensor. If displayed value is less than 133 kPa, check for poor terminal contact is pressure sensor connector, switching solenoid connector or ECM connector.
  4. Check vacuum hose routing to pressure sensor. Check filter in-line with vacuum hose to intake port. Repair or replace as necessary. If vacuum hose is okay, go to next step.
  5. Turn ignition off. Using a jumper wire, jumper test mode connectors (located behind left side of dash). Turn ignition on. Check if switching solenoid is clicking on and off (every 1.5 sec). If switching solenoid is clicking, replace pressure sensor. If switching solenoid is not clicking, replace solenoid.
