Default What happens if you plug a CMP solenoid in backwards?

Does anyone know how much damage if any is done when the intake & exhaust Camshaft position actuator solenoids are plugged in wrong? I believe the connectors were put on backwards as in the locking latch on the wire harness connector was not on the same side as the locking nub on the solenoid. I thought the connectors were keyed so you couldnt get it wrong but apparently he got it wrong. My Malibu was throwing a P0013 which is why he changed the solenoids to start. after fixing that the car threw a P0106, which is the MAP sensor so we replaced that too now its giving us a P0014 which takes us right back to where we started, so I'm wondering if him plugging the connectors in wrong might have damaged something else.

I supposed it is possible you damaged the solenoid by applying power in the reverse direction. It is hard to believe the plug could be attached backwards. Test the solenoid with an ohmmeter you should have no more than 12 ohms but it still could be mechanically damaged due to the plug reversal.

Do you think it could damage anything else? I bought new solenoid's and got MAP sensor error, replaced the MAP only to get another code for the CMP. I'm wondering if plugging them in incorrectly could have messed up the system or did something to the ECU....

Did you replace the new solenoid that had the plug installed backwards with another new solenoid? Are you clearing the codes after the solenoid installation?
