ok p0683 occurs when the PCM carries out a functional key ON, engine running (KOER) self-test for the glow plug system. During that test the PCM enables the GPCM and monitors the GPCM/PCM communication circuit for concerns. When the PCM detects a concern with a GPCM/PCM communication circuit, the DTC is set. possible causes:
  • GPCM/PCM communication circuit open in the harness
  • GPCM/PCM communication circuit short to ground in the harness
  • GPCM/PCM communication circuit short to voltage in the harness
  •  

    p0528 is when the powertrain control module (PCM) uses the fan speed sensor (FSS) input to monitor the cooling fan clutch speed. If the indicated fan speed is lower than the calibrated value during the key ON engine running (KOER) self-test, the diagnostic trouble code (DTC) is set. possible causes:

  • FSS VPWR circuit open in the harness
  • FSS PWRGND circuit open in the harness
  • FSS circuit open in the harness
  • FSS circuit short to voltage or ground in the harness
  • Damaged FSS sensor
  • Damaged PCM
  •  

    The weird code you have is the p0487 which is a code for a egr throttle plate and the 2007 model didn't get a throttle plate which tells me that possibly you have a programming issue with your pcm and you need to have it reflashed which could be covered under warranty if there is an open recall on your vehicle
