The solution is here :
P3321 Possible Solution:
Power Steering Pressure (PSP) Switch Signal Malfunction The PCM counts the number of times vehicle speed transitions from 0 to a calibratable speed. After a calibratable number of speed transitions the PCM expects that the PSP input should have changed. This DTC is set if the transition is not detected. Vehicle towed with engine running Power steering hydraulic concern was repaired but DTC was not erased PSP switch/shorting bar damaged SIG RTN circuit open PSP circuit open or shorted to SIGRTN PCM damaged Check, if possible, if vehicle was towed or power steering service was performed. Observe PSP V PID while checking wires for intermittents.

The poor running symptoms are consistent with a MAP sensor malfunction. In addition, in some cases, a bad MAP sensor will not throw a code. Again, the ELD code likely represents a separate wiring issue.
P3321 OBD-II Diagnostic Powertrain (P) Trouble Code DescriptionP3321 engine trouble code is about Shift Solenoid E Performance or Stuck Off.Main reason For P3321 CodeThe reason of P3321 OBD-II Engine Trouble Code is Manifold Absolute Pressure/Barometric Pressure Circuit High Input. |
P3321 DTCs may also be triggered by faults earlier down the line. For example, a dirty MAF sensor might be causing the car to overcompensate in its fuel-trim adjustments. As a result, oxygen sensors are likely to report fuel mixture problems.
