Error Code P2601: What It Means & What To Do?

<<See All OBD Codes    

The trouble code P2601 can be explained as Coolant Pump "A" Control Circuit Range/Performance. This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model. The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile.

If the engine control module would detect a variation in the voltage coming from the coolant pump "A" control circuit that is outside the parameters set by the automobile manufacturer, then it would store the P2601 error code. This would also give rise to the illumination of the check engine light.

What causes this problem with the Coolant Pump "A"Control Circuit Range/Performance?

• Some issues related to the coolant pump
• Unlocked coolant pump harness
• Unsatisfactory electrical connection in the coolant pump circuit
• Malfunctioning powertrain control module

1. Automatic Transmission Module - Sometimes the transmission module is unable to communicate or correctly anticipate the speed of the vehicle and thus creates difficulty in gear shift leading to sluggish acceleration, throttle response and stalling. Thus can also hamper a lot of components physically and thus must be checked and replaced, if required.
2. Fuel Injector - If there is a leakage in the fuel injectors, then it might cause a rise in the fuel consumption, fuel odours around the vehicle and hard starting. You can always rely on us as we have the best auto parts for our customers.
3. Engine Control Module - If there is any corrosion or breaks in the internal wiring of the harness, then it can cause a short in the ECM or can also cause corrosion in the ECM through the wiring harness. You can always rely on us as we have the best auto parts for our customers.
4. Powertrain Control Module - The onboard computer, or powertrain control module is the brain of the engine control system. Now if the brain is not working properly, then neither is the car engine. Get it replaced before the situation gets worse.
5. Electronic Control Unit - Is your car jump starting on reverse polarity? Or are you facing some intermittent starting issues? If yes, then it indicates that your electronic control unit is bad. So it is very important to replace the defective electronic control unit with us at equitable prices.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2601 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.
• Then the mechanic has to check the wires, connectors and other electrical components and quickly replace them if he finds them to be damaged or defective.
• Make sure to retest the entire system after repairs are completed so that you achieve success. After that the ground wire and ground strap should be inspected and then monitor the coolant pump control relay.
• If no results have been found after these inspections, then a specialized CAN scanner should be hooked up.
• The control modules can be inspected with the help of diagnostic scanner. Now once any component has been restored, then the technician should stop the inspection, the trouble code should be reset.
• After that restart the vehicle and then inspect for the P2601 code. This is done so that the mechanics is alerted as soon as the problem is resolved.
• 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.

Common Mistakes When Diagnosing The P2601 Code

• Common mistakes while diagnosingthis trouble code are unnecessary and expensive replacements which usually happens when one doesn't follow all the steps carefully.
• 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 the help of experienced diagnostician to avoid any mistakes.
