    Anyone know what this code is? I just had my radiator changed and this code showed up around 200 miles later. The dealer must have removed the intercooler because I've been getting low IC level whenever I really get on it since I left the dealer. I've been topping off the tank as needed.

    What is this code? I am getting it now too :S I also am getting warnings about the IC coolant level but it was fine when I looked at the tank.

    Thanks for the reply! I will let the dealer handle it Monday.

    Possible Air Bubble in the system? Not sure, we have a lot of heat exchangers that have been installed around the country and have yet to experience this code. When we install at the shop we always bleed all of the air out of the line before starting, bleeder is located on the passenger side of the supercharger above the coolant lines. My self and Eric from ID both have had an exchanger installed since august and have never seen that code.

    I just got this code today after having the bwoody heat exchanger installed. Any ideas how to resolve this issue? Anybody know exactly where the bleeders are?

    P0EA7-LTR PUMP PERFORMANCE

    Theory of Operation

    To improve engine performance the Charge Air Cooler (CAC) system is used to cool the charge air. The Charge Air Cooler (CAC) reduces the charge air temperature increase caused by the supercharger. The CAC system consists of an electric CAC Pump, Charge Air Coolers, Coolant Reservoir, Charge Air Cooler Radiator, Charge Air Cooler Coolant Temperature Sensor and plumbing. The CAC system operates independent of the vehicle’s primary cooling system.

    The CAC Pump is a smart device that contains a LIN Bus communication module and a coolant pump. To maintain a desired charge air temperature, the PCM sends a pump speed command over the LIN bus to the internal CAC pump module. The internal CAC pump module controls the pump speed/coolant flow rate using Pulse-width modulation (PWM). The CAC Pump assembly monitors for internal system circuit and performance failures. If a fault occurs the CAC Pump module sends the fault information to the PCM through the dedicated LIN Bus. The PCM processes the information received, then sets the correlating fault.


    When Monitored and Set Conditions

    When Monitored: This diagnostic runs continuously when the following conditions are met:




      • With the engine running.
      • No active circuit faults for the Charge Air Cooler Pump Assembly.
      • Charge Air Cooler Pump Assembly above a minimum calibrated threshold.

    Set Conditions:




      • The PCM receives a LIN bus message from the Charge Air Cooler Coolant Pump that the pump current is either much greater than, or less than expected at a particular rpm.

    Default Actions:




      • The MIL light will illuminate.
    Possible Causes
    BLOCKAGE IN THE COOLANT FLOW
    LOW COOLANT / NO COOLANT
    EXCESSIVE AIR IS MIXED WITH THE COOLANT
    CHARGE AIR COOLER COOLANT PUMP



    best way to prevent air in the system is to use a vacuum refiller tool.

    Agreed, you definitely have an air bubble in the system.

    So have driven around a few times and then jacked the pass corner up to "burp" the system. Each time the reservoir went down about a 1/4" below the full mark. This last time the fluid level didn't go down so hoping that means I got the air out. Will the SEL light go away on its own or do I need to have someone clear it?

    The MIL should extinguish after the monitor passes on 3 consecutive trips.

    Unfortunately still there and I think the IC coolant temps seem higher than they should for 82 degrees. image.jpeg

    Man this CEL is driving me nuts! Driving around for 2 weeks and still get the I/C error. The first few times I had to add coolant because it was low. Now it's not going down any more but I still get the light. I have also cracked the bleeder several times. I guess I am going to have to take to the dealer and see if they can figure it out.
