I have a 2003 dodge ram this code shows up po354 what does this mean

If the code is P1686, it means No CCD bus messages received from the Smart Key Immobilizer Module (SKIM).
If it has any other prefix (B, U, etc), I don't know what it means.

well to start with those aren't codes you didnt read the instructions for your scanner ----rescan and when you see these codes continue to the next page to get the codes

Transmission malfunction. This is generic. Get a better code reader and see what the codes are. Like P0733. 3rd gear ratio.

if you have a tilt wheel,you may have a broken wire,replace the whole colunmb also,,,,,,,,,,,,,(pics)look for 2 and 7 ,,blend door actuators,,

The P1693 is a turbo charger control circuit malfunction

P0132 is O2 sensor High circuit sensor voltage sensor 1 bank1, What this mean is either you 02 sensor on bank1 (or where cylinder 1 is located) is disconnected internally or extenally you will need to inspect the harness for any disconnection if connection is good then you will need a new 02 sensor

it's for a bad coil pack or COP, coil on plug

there is a directional door actuator motor,that has gone bad.

This code means that system to lean, bank 1.
some of the possible causes to make this code set are
1. intake or exhaust leak,
2. problem with the air system.
3. MAF (Mass Air Flow sensor)VAF sensor (Volume air flow sensor)
4. fuel pressure/pump
5. injector(s)
6. HO2S (Oxygen sensor)

Heryou go its a pretty lengthy diagnostic procedure it appears there is a power problem with the instrument cluster here is the code meaning hope it helps have a good dayDB
