Does the ODBII scan code p1372 mean a manufacturer code?

Answer 1

Yes, the P1372 code is a Ford DTC (diagnostic trouble code)

According to the information below, plus a quick search (dogpile.com), the P1372 code indicates "P1372 Early Ignition Coil Activation Fault Coil 2" I haven't found a diagnostic as to what that really means, but it's a start.

Here's a break-down of the scan codes I find helpful:

First digit structure is as follows:

• Pxxxx for powertrain

• Bxxxx for body

• Cxxxx for chassis

• Uxxxx for future systems

Second digit structure is:

• P0xxx Government required codes

• P1xxx Manufacturer codes for additional emission system function; not required but reported to the government

Third digit structure is:

• Px1xx measurement of air and fuel

• Px2xx measurement of air and fuel

• Px3xx ignition system

• Px4xx additional emission control

• Px5xx speed and idle regulation

• Px6xx computer and output signals

• Px7xx transmission

• Px8xx transmission

• Px9xx control modules, input and output signals
