![]() ![]() Chevrolet Camaro: LS/LT to SS Front Bumper Conversion (For 2010-2013 models).There are a lot of things that you can check yourself when diagnosing P0607 in the Pontiac Vibe, but if you can’t find something wrong, take it to someone who has expertise in these things before buying a new PCM. Again, make sure there are not TSB’s for your model year Vibe The PCM may need to be replaced, or a reflash. Follow the wire from the fuse panel to the PCM. It is possible that the power wire going to the PCM has become damaged or shorted out. If there appears to be any rust or corrosion, unbolt it and clean the mating surfaces with sandpaper. Make sure that it is tightly bolted to the frame. Once you find it, confirm that the wire wasn’t damaged in any way. You’ll need to find the pinout schematic for your specific model year Vibe’s engine and find the ground pin and trace it to where it’s connected to the chassis. If the battery looks good and tests ok, check the ground wire that runs to the PCM. It would be best to start with the battery tested since testing is easier to do than the alternator.Įven if there is no battery light, the battery still can be the cause of P0607. It can also mean there’s a bad alternator. The battery light can mean that the battery is bad. If your battery light has been coming on while driving, it is likely related to P0607. Almost anywhere that sells batteries can test it for you. If the battery has gone bad, it can sometimes affect the performance of the PCM. A piece of sandpaper or wire brush will work fine if you are in a pinch. If your battery terminals are corroded, the local parts store will sell a battery terminal cleaner that will go right over the battery posts and in the terminal. This leads to it not being able to consistently read everything the engine is doing (or function at all). If the terminals are corroded with battery acid (or if they aren’t tightened all the way) this can cause the voltage going to the PCM to fluctuate. Your Vibe’s PCM needs a consistent level of voltage from the battery. TSB’s are communications that Pontiac uses to cover known issues with a vehicle, as well as how to deal with them. Make sure there isn’t a Technical Service Bulletin related to the PCM of your Vibe. This section gives you the common causes of P0607 in order from easiest to check to hardest, ending with the PCM itself. These onboard computers are designed to last the life of your Vibe and rarely fail. Limp mode- If the PCM has a limp mode protocol, it may engage it to help you get home.This can happen while the vehicle is moving down the road. If the PCM isn’t functioning properly, the engine likely isn’t getting any spark. Won’t start– This is a common symptom of P0607.P0607 can have different symptoms depending on how far the PCM has been compromised. So it has to be functioning in some capacity if you are able to pull the code. Trouble codes are stored in your Vibe’s PCM memory. The PCM has detected that it is not functioning properly and has thrown P0607. Without the PCM, a modern vehicle’s engine will not run at all. It takes all of the data from the Pontiac Vibe’s various sensors and uses it to control spark timing, the air-fuel mixture, idle speed, etc… The control module is commonly referred to as the powertrain control module (PCM) or the engine control module (ECM). P0607 has a two-part meaning: Control Module P0607 Definition: Control Module – Performance P0607 is most commonly caused by a bad PCM/ECM, battery, or wiring to and from the PCM. P0607 is a general OBD2 diagnostic code, meaning it has the same meaning for the Pontiac Vibe as it would any other vehicle. ![]()
