A/T Clutch Pressure Control Solenoid Valve B Test
  1. Connect the HDS to the DLC (A) located under the driver's side of the dashboard.
  1. Turn the ignition switch to ON (II). Make sure the HDS communicates with the PCM. If it does not, go to the DLC circuit troubleshooting; R20A3 engine model, K24Z3 engine model.
  1. Select Clutch Pressure Control (Linear) Solenoid Valve B in the Miscellaneous Test Menu, and test A/T clutch pressure control solenoid valve B with the HDS.
    • If the valve tests OK, the test is complete. Disconnect the HDS.
    • If the valve does not test OK, follow the instructions on the HDS.
    • If the valve does not test OK, and the HDS does not determine the cause, go to Step 4 .
  1. Remove the battery base.
  1. Disconnect the connector (A) from A/T clutch pressure control solenoid valve B.
  1. Measure the resistance between A/T clutch pressure control solenoid valve B connector terminals No. 1 and No. 2.
    Standard:
    3−10 Ω

  1. Connect a jumper wire from the negative battery terminal to A/T clutch pressure control solenoid valve B connector terminal No. 2, and connect another jumper wire from the positive battery terminal to A/T clutch pressure control solenoid valve A connector terminal No. 1.
    • If a clicking sound is heard, the valve is OK. The test is complete, reconnect the connector, then go to Step 20 .
    • If no clicking sound is heard, go to Step 9 .
  1. Disconnect the connector (A) from A/T clutch pressure control solenoid valve C.
  1. Remove the harness clamps (D) from the clamp brackets.
  1. Remove the mounting bolts and A/T clutch pressure control solenoid valves B and C with the clamp bracket (E).
  1. Remove the ATF joint pipes (F), the O-rings (G), and the gasket (H) from the transmission housing.
  1. Check the fluid passage of A/T clutch pressure control solenoid valves B and C for contamination.
    If necessary, clean the A/T clutch pressure control solenoid valve body.
  1. Connect a jumper wire from the negative battery terminal to A/T clutch pressure control solenoid valve B connector terminal No. 2, and connect another jumper wire from the positive battery terminal to connector terminal No. 1. Make sure A/T clutch pressure control solenoid valve B moves.
  1. Disconnect one of the jumper wires, and check the valve movement at the fluid passage in the valve body mounting surface. If the valve binds or moves sluggishly, or if the solenoid valve does not operate, replace A/T clutch pressure control solenoid valves B and C.
  1. Clean the mounting surface and the fluid passage of the transmission housing.
  1. Install a new gasket on the transmission housing, and install the ATF joint pipes.
    NOTE: Be sure to install a new gasket with the blue side toward the transmission housing.
  1. Install new O-rings over the ATF joint pipes.
  1. Install A/T clutch pressure control solenoid valves B and C with the clamp bracket.
  1. Check the connectors for rust, dirt, or oil, clean or repair if necessary, then connect the connectors securely.
  1. Install the battery base.
