P1229 error code

if the motor wont start
i would start at the pedal
its the one thing that seems related to a not start

Check harness body ground
- Faulty Accelerator Pedal Position (APP) sensor -
-Faulty Power Steering Pressure (PSP) sensor
- Faulty Refrigerant Pressure sensor
- Faulty EVAP Control System Pressure sensor

The oil light is warning the driver the engine has no oil pressure. That could be due to the engine oil level being low, or because of a problem with the oil pump.
is it possible you unplugged or damaged the oil pressure switch on the engine ?

Here is the description for the code. You need to check the sensor and the wiring back to the computer.

P0551 DODGE Description Power steering pressure (PSP) sensor is installed to the power steering high-pressure tube and detects a power steering load. This sensor is a potentiometer which transforms the power steering load into output voltage, and emits the voltage signal to the Powertrain Control Module (PCM). The PCM controls the electric throttle control actuator and adjusts the throttle valve opening angle to increase the engine speed and adjusts the idle speed for the increased load.

You need an OBD2 scanner to read the error code. It plugs in to your car and is typically under the steering wheel. Autozone will read the error code for free.

i would check the power steering fluid to make sure it isn't low. if that checks out then i would just keep an eye on it.

look on or near your actual pump or near your fluid resevoir. should connect to a wire harness.

it is a small sensor on pump just need a ratchet and socket it is a one wire sensor like old oil pressur sensors just tug wire it will come off

P2187 System Too Lean at Idle (Bank 1)

Check the MAF. this could be the reason for the O2 reading lean. if the MAF is ok and, the sensor is not damaged, replace the Os sensors.
