WARNING: This page is about a different car, the 2003 Lexus SC 430, 2003 Lexus LS 430, 2003 Lexus IS 300, 2003 Lexus GS 430, and 2003 Lexus GS 300. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
For SC430, see DIAGNOSTIC TROUBLE CODE DEFINITIONS
in SELF-DIAGNOSTICS - SC430 article.
- If PNP switch is out of adjustment, voltage signals may not be correctly applied to ECM, causing a Diagnostic Trouble Code (DTC) to set. Before assuming PNP switch is faulty, adjust PNP switch. See PARK/NEUTRAL POSITION (PNP) SWITCH under SENSORS & SWITCHES in REMOVAL & INSTALLATION - EXCEPT GX470 article.
- After switch adjustment is completed, recheck for codes. If DTC does not reset, PNP switch is okay. If DTC resets, remove PNP switch. Check for continuity between specified terminals of PNP switch. See PNP SWITCH CONTINUITY table. See Fig 1. If continuity is not as specified, replace PNP switch. If continuity is as specified, install and adjust PNP switch.
