P007c
Hey everyone,
I have been repeatedly having the check engine light come on with the code P007C (Charge Air Cooler Temperature Sensor Circuit Low) going off.
It isn’t consistent, it seems to occur most frequently in cooler weather (40-50F) with a warmer engine on restart, and it has gotten more and more frequent.
Truck is a 2012, and is EGR/DPF deleted with H&S Minimaxx running on the stock “Performance” tune.
Any thoughts or help would be greatly appreciated.

The pin is attached FYI
P007C - Charge Air Cooler Temperature Sensor Circuit Low (Bank 1)
Description: The powertrain control module (PCM) continuously monitors the CACT circuit for concerns. The test fails when the temperature is greater than the calibrated value for the sensor or a short to ground is detected in the circuit.
Possible Causes: Damaged CACT sensor
CACT circuit short to ground
VPWR circuit open
Low air flow through the charge air cooler (CAC)
Damaged harness connector
Damaged harness
Diagnostic Aids: The presence of this DTC may indicate that the vehicle is operating in derate mode and may experience a loss of power.
Check the harness for intermittent concerns, incorrect connections, routing, alterations and damage due to contact with other components.
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test FB .

Location in case you need it
There have been some cases of corroded connectors lately, mostly on the MAF sensor so you may want to take a look at the connector??
Otherwise, ya, I agree with Joel. Throw a new one at it
Thanks

I was throwing P007E for CAC Temp Sensor Erratic/Intermittent
(P007E)
For me, I replaced the sensor but it continued being a problem. It was corrected by an update for '13 tuning from H&S. Not sure if that would help you if you haven't updated in a really long time.
Otherwise the sensor PN was DY-1146 - about fifty bucks Canadian. Very easy to change on the outlet of the CAC as shown in previous posts.
Hope it helps!

Thanks guys - I will order the sensor, I'll be back in the states in a month, and can pick it up then. I'll also check H&S for updated tunes. I last updated the tuner early 2014.
On edit: Wow, sensor is only $12 from Autonation White Lake

Just to revisit this - I've been busy, but was able to reprogram my H&S with the latest tunes. Took 4hrs to download here in Aus!
Anyway, didn't alleviate the code by itself. I have a replacement sensor here that I have ordered, and hope/assume that will fix it once I fit it.
