That is a average price for PCM replacement.
Engine breakdown is possible if not fixed and still driven. The possible caused are very simple to test and most likely the shop is correct of what is wrong.

Possible Causes:
(K454) MDS SOLENOID NO. 7 CONTROL SHORT TO VOLTAGE
(K454) MDS SOLENOID NO. 7 CONTROL SHORT TO GROUND
(K454) MDS SOLENOID NO. 7 CONTROL OPEN
GROUND CIRCUIT OPEN
MDS SOLENOID NO. 7
POWERTRAIN CONTROL MODULE (PCM)
