Diagnostic Trouble Code Identification: Notes
NOTE:
This diagnostic information applies to 1997-2000 models with 2.3L engine (No.111), equipped with Motor Electronics Sequential Fuel Injection (ME-SFI).
NOTE:
When connecting test equipment, disconnect Engine Control Module (ECM) connector "D" first. When reconnecting connectors, connect connector "D" last. See ECM CONNECTOR IDENTIFICATION .
Use DTC identification to identify possible cause, then proceed to indicated area under TEST STEP/REMEDY column.. Before proceeding with diagnostic testing, see HOW TO READ DIAGNOSTIC INFORMATION . Some diagnostic information is identified by chassis/model number. See MODEL IDENTIFICATION .
If there is no DTC indicating no malfunction in system, and there is a complaint, perform FUEL INJECTION SYSTEM TESTS , IGNITION SYSTEM TESTS , ELECTRONIC ACCELERATOR TESTS and CRUISE CONTROL TESTS entirely.
