hi my name is kenny melancon I placed a few notes on here about your code issue, I have fixed my car by cleaning the throttle body no replacement of any parts, I can explain the code to you if you wish , my car has never set the code again. and I have also fixed 4 other cars the same way

Good job taka

So cleaning the throttle body fixed yours as well as it fixed mine PS 2006 SUBARU TEST IN OHMSHOLDING THE SENSOR WITH THE DENSO NUMBER FACING UP AND GOING FROM LEFT TO RIGHT ON PIN TERMINALS AFTER TESTING TPS I FIND NOTHING WRONG WITH TPS. WILL CHECK PIN DRAG ON CONNECTOR. HAVE CHECKED THE PIN DRAG OG THE TERMINSALS USING A .033 in spade terminal the drag felt thwe same on all 6 terminals. Terminals tested ok at the connector to the TPS. I removed the intake throttle and found it was carboned up and in need of cleaning/service. I removed the intake throttle body and cleaned carb spray. Looks like brand new, Now there is a gap in the plate when it is in closed position. So lets review the code P1238 $ 10 which says throttle / pedal position sensor Switch D / E voltage correlation. It does not say there is a voltage loss. Reading between the lines the voltage is there and the computer is programmed to read a certain voltage at a certain position of the tps and the throttle intake. There is a certain percentage of tollerance or voltage to be read as a example 1.0v to 1.2 volts , if this voltage is not seen within lets say 5 seconds a code P1238 will set and this is because the throttle plate is sticking. Let me also add that this code is temperature related, The code sets form cold start to warm operating temperatures. The throttle plate is sticking inside the throttle body because of the sludge build up around the inside of the plate. Once the throttle body is serviced/cleaned the plate will move freely without sticking because of the sludge build up in the intake throttle body. I will attach a picture of the throttle place after cleaning ,,This is what is must look like. Do not bend or adjust the plate in any way, just clean the sludge.Bitmap PIN 11 - 2 = OPEN1 - 3 = OPEN1 - 4 = OPEN1 - 5 = .482 K OHM IDLE 1.693 K OHM FULL THROTTLE.
