The factors that influence the cost of diagnosing and fixing the P1E04 automobile fault code based on the estimated repair time of 1.0 hour are: – The hourly rate charged by the auto repair shop, which can range from $75 to $150 per hour. – The complexity of the issue causing the fault code, which can affect the time required for diagnosis and repair. – The availability of replacement parts, which can impact the cost of the repair. – The expertise and experience of the mechanic performing the repair, which can affect the efficiency and accuracy of the diagnosis and repair process.

The P1E04 code refers to a fault in the HybridElectric Vehicle battery pack.

The battery pack contains 288 cells grouped in parallel and in-series.

There are three battery sections, each with a different number of cells and cell groups.

The battery energy control module monitors the voltage of the 96 battery cell groups through the hybridEV battery interface control modules.

The battery energy control module will determine when a fault condition is present and communicate it to the hybridEV powertrain control module 2.
