P0607 – Control Module Performance Code basically the ‘electric brain’ of the vehicle. And with that, it is responsible for monitoring every aspect of the vehicle’s engine, various electronic functions including the system’s anti-lock braking system, traction control system, electronic stability control, power steering assist, electrical system, and other advanced engine/transmission functions.

What Does This Mean?

This Diagnostic Trouble Code (DTC) is a generic transmission code, which means it applies to OBD-II equipped vehicles. Although common in nature, specific repair steps may vary depending on the brand / model. This code basically failed PCM / ECM (Powertrain / Engine Control Module) programming. This can be a more serious code and can also be called an ECM internal circuit error.

Symptoms:

Code P0607 will illuminate MIL (Malfunction Indicator Light). Other possible symptoms of P0607 include:

➢ The car can also go into homeless mode when running on low power.

➢ No start condition (starts but doesn’t start)

➢ May stop working while driving

➢ Decreased engine performance

➢ Anti-Lock Braking System

Causes:

P0607 could be for one or more of the following reasons:

➢ Loose ground terminal at PCM / ECM

➢ Battery discharged or defective (main 12V)

➢ Open or short circuit in power or ground circuit

➢ Loose or worn out battery terminal

➢ Defective PCM / ECM

➢ Poor Connections in the Wiring System

➢ Alternator is malfunctioning

➢ PCM software in need of an update

How to Diagnose Tools You Need Process:

As a car owner, there is not much you can do to diagnose this DTC. The first thing to check is to check the battery, voltage, loose / worn out terminals etc. and do a load test. Also check the ground / wiring at PCM. If this is true, then other common solutions P0607 Performance Control Unit e DTC either replace PCM or update (reprogram) PCM with updated software. Be sure to check for TSBs in your car (service bulletin) as some Toyota and Ford cars have this TSB code known as P0607.

If PCM replacement is required, we strongly recommend that you visit a qualified repair shop / technician who can re-program the new PCM. Installing a new PCM may require special tools to program the vehicle’s VIN (vehicle identification number) and / or anti-theft information (PATS, etc.).

How to Fix the P0607 Code:

Though P0607 is a generic trouble code, there is no universal solution that works for all vehicles. Repair procedures may change per vehicle.

If you’re not equipped with the knowledge and tools needed to do the repairs, it’s best to leave the work to a mechanic. However, if you really prefer to fix this code yourself, then we suggest consulting a vehicle-specific repair manual or subscribing to an online repair database.

Common mistakes:

The following are common mistakes owners make when diagnosing this issue:

➢ Replacing the ECM when other components could be causing the issue.

➢ Not checking for damaged or corroded battery cables

➢ Failing to use OEM parts

➢ Not testing with proper diagnostic tools

➢ Not testing while driving for conditions that would cause symptoms

➢ Not testing for voltage drops in wiring

Replace/Repair These Parts To Fix OBD Code P0607:

Engine Control Module A faulty ECM has to be instantly replaced to avoid system malfunctioning.

ECM Wire Harness If there are any broken wires or cuts, fix them immediately

Vehicle’s Alternator If your alternator is damaged it will be difficult to charge the battery. Change the damaged part.

Electronics Control Module The damaged component has to be replaced immediately to avoid malfunctions.

How much does it cost to fix the P0607 code?

A new Control Module could be as much as $500. Replacing a bad Control Module is not a guarantee that the issue will be transformed/ resolved either, especially if it was caused by a faulty battery cable or alternator. The costs of replacing damaged wiring elements can be expensive but may save you from further damage later on due to poor wiring or electrical connections.

If your vehicle does have strong electrical damage due to corrosion or water damage, this would most likely indicate there is more serious internal damage and would need professional assistance from a mechanic or technician to diagnose it rightly and accurately.

Conclusion:

There are a lot of things that you can check yourself when diagnosing P0607, but if you can’t find something wrong, take it to someone who has expertise in these things before buying a new PCM.
