Class problem

[Cruze]

Hi guys, I have an 86 Royale . The class system was showing E4....solved that by resoldering the nine pins at the back of the plug. Now I have an E1 fault code.... How do I cure this one please....?

Thanks in advance...

"E1" error may encompass a broad range of defects.

• Faulty connections.
  
• Faulty discharge valve (solenoid).
  
• Low pressure sensor input voltage. (Low battery or low voltage due to poor connectors)
  
• Faulty pressure sensor.
  
• And finally, incomplete solder repair at the nine pin board connector.

Same issue with my 86, ended up changing the compressor assembly. About a year later I removed the system and added schrader valves and bought a portable 12v compressor from Harbor Freight for $9.00 and never looked back. and I can air up my tires if needed.
