DTC P1588 Cruise Control Clutch Control Circuit High P1536 Engine Coolant Overtemperature - Air Conditioning (A/C) P1515 and P2135 are set only when our familiar P1518 is NOT present, which would explain why these two codes hadnt yet appeared. Both of these potential culprits could be easily attributable to the engine recently being swapped. The loss-of-power complaint couldnt be duplicated so, to cover our bases, we voltage-dropped all powers and grounds and cleaned the throttle plate and body. We pressed on the gas pedal and it seemed like the care kept slowing down. Condition/Concern: Customers may have a concern of lack of power and engine light on. So, to paraphrase the immortal words of Yogi Berra, we reached a fork in the road and we took it by replacing the ECM. P1558 Cruise Control Servo Indicates Low Pasted as rich text.
