P0B98 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P0B98 can be described as Hybrid Battery Voltage Sense “S” Circuit High Issue. Is your vehicle’s check engine light illuminated? Are you experiencing sudden decrease in engine power and acceleration? Is there a drop in the fuel economy with increased level of emissions? All these indicate the problem with the car’s hybrid battery and the powertrain control module, thus flashing OBD Code P0B98 error.

Don’t worry if P0B98 error code is triggering again and again. We offer wide range of auto parts at affordable prices to our dear customers. The high voltage battery is composed of many individual battery cells. The Battery Energy Control Module (BECM) monitors all the cells in the high voltage battery pack to make sure they are all contributing equally to the high voltage system. If one cell is determined to be unequally contributing, code P0B98 will be set. The powertrain control module (PCM) monitors the hybrid battery “S” circuit voltage issue. The PCM sets the OBDII code when the hybrid/electric battery “S” circuit voltage signal is out of factory specifications.

What causes this problem with the Hybrid Battery Voltage Sense "S" Circuit High?

• Hybrid battery pack malfunctioning
• Hybrid battery pack harness and wiring open or short
• Hybrid battery pack circuit and connectors faulty
• Powertrain Control Module faulty

For us our customers are everything, and that’s why we will help you to diagnose P0B98 code by mentioning some important symptoms below:

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0B98 code to be stored:

• The mechanic or the technician will use a diagnostic scanner or code reader like DVOM to visually scan for the error codes in the vehicle.
• After performing a careful inspection, every of the stored codes and freeze frame data are retrieved as it can help down the way for further diagnosis process.
• Most often he has to inspect the solenoid itself to see if they are faulty or damaged. Additional error codes that are stored in the vehicle are also addressed.
• The mechanic performs a continuity test between the PCM and solenoid to check the resistance.
• If the solenoid or the control modules are not faulty, he will then retune the code and test drive the vehicle.
• On test driving, if the P0B98 code does not return soon, he will know that an erratic condition exists.
• But if the error returns instantaneously, he will check every components of the control module as well as the circuit like connectors, wires, harness, fuses, etc. for any possible fault.
• If any component is damaged, he will fix them right away.
• After performing this repair, he will inspect the transmission fluid as well as its level.
• If the level is below the manufacturer’s specification, it has to be refilled and if the fluid is murky or contaminated it needs to be replaced.
• Every time a repair work is carried out, make sure that the mechanic test drives the vehicle after every repair so that the diagnosis is successful. This can eventually help him to know as to where the error occurred.
• A sure sign of this is smoke or steam being emitted from underneath the hood. The ignition timing could be set incorrectly and will require adjustment.
• A noticeable pool of fluid underneath the car could be a sign of the cylinder head gasket failing. That can cause billowing smoke being blown from the exhaust system.
• A dirty MAF sensor might be causing the car to overcompensate in its fuel-trim adjustments. As a result, oxygen sensors are likely to report fuel mixture problems.

Common Mistakes When Diagnosing The P0B98 Code

• Battery contactor assembly issues
• Hybrid Battery circuit issue
• Faulty battery harness and connectors
• Energy Control Module faults
