Download SYMPTOM The MIL is on, and DTC P2195 (rear air fuel ratio sensor signal stuck lean) or P2197 (front air fuel ratio sensor signal stuck lean) is set. PROBABLE CAUSE The ECM/PCM software incorrectly interprets sensor inputs, causing the codes to set. CORRECTIVE ACTION Using the HIM (Honda Interface Module), update the ECM/PCM with the iN monthly CD, dated August 2004 or later. REPAIR PROCEDURE NOTE: • Before you update an ECM/PCM, make sure the battery in the vehicle is fully charged. • To prevent ECM/PCM damage, do not operate anything electrical (audio system, brakes, A/C, power windows, moonroof, etc.) during the update. 1. If not already done, load the May 2004 or later iN CD onto the iN master terminal. Loading instructions are included with the CD. 2. Update the ECM/PCM software with the HIM. For updating instructions, refer to Programming the HIM and Updating an ECM/PCM With a Programmed HIM in Service Bulletin 01-023, Updating Control Units/Modules. 3. Warm up the engine to operating temperature, then shut if off.
