If this has a catalytic converter it has a MAP sensor.

ok that came up more like it
J006V01505F (H135FT)

ok the first code you listed: DTC 522637-3 - Pre-Cat Bank 2 Short Term Fuel Correction Railed Lean
Problems that can cause a lean code could be:
- low fuel pressure
- partially blocked fuel injectors
- manifold vacuum leaks
- defective O2 sensor
- a misfire on one or more cylinders
- exhaust leak ahead of the O2 sensor
- faulty MAP sensor

the DTC 522633-2 code
Pre-Cat Bank 2 Short Term Fuel Correction Railed Lean
same as above

DTC 105-5
Intake Air Temperature (IAT) Sensor Open Circuit
open circuit in sensor input or ground circuit
check connection between ecu and sensor
if all checks show less than 0.5ohms then replace sensor

DTC 106-4
Manifold Absolute Pressure (MAP) Sensor OORL
check sensor voltage, should be 5v between + and - pins at sensor harness connector.
If not 5v measure from frame ground on - side.
if 5v then sensor ground has open circuit and and wiring should be repaired.
if 0v sensor supply has open circuit and wiring should be repaired.

Now i do find it odd that it has all these error codes all at once
have you been pulling connectors checking circuits at all?
if you unplug something even if the truck is not running it may still register a code because you break the power circuit and the ecm will see that and pop a code. the ecm does hold power for a period of time even after the engine is turned off so the circuits will still be live and expect to see a connection there.

i would check the frame grounds too
and if you have the laptop program definitely watch the run-time screen and see what the O2 sensor is doing

Ok got three other codes 522633-2, 522637-3 105-5, 106-4
This unit LPG and doesn't have a MAP sensor or fuel rail. Any ideas. May throttle position? LPG convertor? We need to have this unit up and running to day
Thanks again

This code is for a lean condition on pre-cat bank 2. Most of the time it is a O2 sensor problem. MAP sensors can also cause this. Low fuel rail pressure is also listed.

that serial number is not complete
what is the ending letter?

what i come up with in hypass when i enter that number it defaults to this: G006V01505B (H155XL2)

but your thread here lists it as an FT model and the service DTC codes do not show up like this.
