Diagnostic Trouble Code Chart

HINT:

If any DTCs are displayed during the DTC check, inspect the circuit listed for those DTCs. For details of each DTC, refer to the page indicated in the DTC Chart below.
Test mode code C1571/71 is stored during the transition to test mode. This code does not indicate a malfunction since the code will be cleared when the ECU determines that the sensor is normal. The test mode code is cleared simultaneously when test mode is terminated.
The P/S warning light remains illuminated during test mode and starts blinking when the speed sensor is determined to be normal.
