2003 Honda Civic Hybrid P1600 and P1563 Code Explanation and Warranty Information

Model: 2003 Honda Civic Hybrid Fault Code: P1563 Posted: 2009-08-14 18:42

I recently had my 2003 Honda Civic Hybrid scanned at AutoZone, where they couldn't locate the codes P1600 and P1563 in their database. I tried searching online but found limited information—some sources don’t list these specific codes for this model year. After checking official Honda resources, I still can’t find clear explanations. I’m wondering if anyone knows what these codes mean specifically for a 2003 Honda Civic Hybrid? Are they related to the hybrid system or battery issues? Given that my car is over 15 years old, I'm concerned about repair costs and whether warranty coverage might apply.

Since this is a hybrid vehicle, it's strongly recommended to have the issue diagnosed only by a certified Honda dealer or an independent mechanic with specific training in hybrid systems. AutoZone and similar auto parts stores typically lack the expertise to interpret hybrid-specific fault codes accurately.

I own a 2005 Honda Civic Hybrid that displayed both P1600 and P1433 codes, which were traced by the dealer to a failure in the lithium-ion battery for the hybrid motor. The replacement cost was approximately $3,000. After the repair, the warning lights have not returned. This suggests that such issues are common in older hybrids with aging IMA (Integrated Motor Assist) batteries.

Thanks for this info—my wife's 2005 Honda Civic Hybrid just started showing the same P1600 and P1563 codes. We were confused because they weren’t listed in our owner’s manual or service book. She has a 10-year battery warranty, so we’re planning to consult with a dealer tomorrow to check if that applies.

P1600 and P1563 are commonly associated with issues in the IMA (Integrated Motor Assist) system and the hybrid battery. Honda extended the IMA battery warranty to 10 years or 150,000 miles in certain states several years ago—some sources now indicate this extension may apply to all Honda hybrids. A July 26, 2011 service bulletin (SB 10-061) suggests broader coverage. Always verify your specific warranty terms, as the extended period was already included in original hybrid warranties for some states. Some Honda service centers are now offering access to this coverage. I’ve owned two Honda Civic Hybrids—my most recent 2005 model showed P1600 and P1433 during extremely hot weather when both the IMA and engine-check lights illuminated. The IMA light turned off after a few days and hasn’t returned, though the engine-check light remains on.
