P0A89 - OBD Trouble Code

<<See All OBD Codes

The trouble code P0A89 can be explicated as 14 Volt Power Module Current Sensor Circuit High. The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile. This code is a generic trouble code, meaning it applies to all vehicles equipped with the OBD-II system, especially those made from 1996 up to present. It’s also more common among Audi, Citroen, Chevrolet, Ford, Hyundai, Nissan, Peugeot, and Volkswagen vehicles. Specifications on the definition, troubleshooting, and repairs, of course, vary from one make and model, powertrain configuration type, to another.

Do you want to gain some more knowledge about the P0A89 trouble code? It is the engine control module which would examine the 14-volt power module current sensor circuit. This trouble code would be set by the ECM when the 14-volt power module current sensor circuit voltage would not be as per the parameters set by the manufacturer. This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another.

Here are some steps which you should follow in order to diagnose this fault code: Start by making a visual inspection of wiring and connectors

• The tools that will be required to diagnose a code P0A89 are a diagnostic scanner, a digital volt/ohmmeter, and a reliable vehicle information source.
• You can always clear the codes to verify that it is not an intermittent condition. Then the vehicle should be taken out for a road test and then the computer should be scanned once more to see if it returns.
• The air injection pump wiring harness should be carefully examined and at the same time you should check the connections for defects.
• Carefully check the air injection pump wiring harness as well as various other connections.
• Examine the system hoses and fittings for excessive heat damage, as well as other situations which due to which a leakage can be caused.
• The system fuses should be tested properly.
• You can always check the one-way check valves to be sure that air is only able to go through one way.
• Make sure to inspect the secondary air injection system pump.

Common Mistakes When Diagnosing The P0A89 Code

Common mistakes while diagnosing this trouble code are unnecessary and expensive replacements which usually happen when one doesn’t follow all the steps carefully. In this code usually people replace 14 Volt power module current sensor without even properly diagnosing it.

The most common mistake while diagnosing this code is missing out on diagnosing steps which further leads to the expensive and unnecessary replacements. It is always recommended to seek help of experienced diagnostician to avoid any mistakes.
