Can you tell me the meaning of the error codes p1600 and p1433 on a Honda Civic Hybrid?

The Honda Civic Hybrid P1433 code suggests a battery failure happening prematurely, while the P1600 code points to voltage issues with your Civic's battery. These codes are often associated with problems in the IMA system and IMA Battery. Honda previously extended the warranty for the batteries to 10 years or 150,000 miles in certain states. A Honda Service Bulletin dated July 26, 2011 (SB 10-061) suggests that this extended warranty may now apply to all Honda Hybrids. It's wise to review your warranty details as some hybrid cars in select states already had this extended coverage period in their original warranty. Before investing $3,000, explore your warranty options. Some reports suggest that some Honda service centers are transparent about the extended warranty.
