What's the 2007 Dodge Caliber code p1607?

If You're seeing fault code P1607 on a 2007 Dodge Caliber (or any other Dodge vehicle for that matter), then You're likely in for some bad news. It means that Your Powertrain Control Module (PCM) has internal shutdown timer slow rationality issues. Your PCM is the most important electrical component in Your car, so it's important that You get this figured out as soon as possible. The most likely cause is a low battery voltage, which is one of the leaSTSevere, so there's some good news. You may also have a faulty alternator, low engine coolant level, poor engine cooling conditions, or a failing powertrain control module. The latter is, of course, the moSTSerious -- and a replacement will set You back several hundred dollars.
