Why am I getting manufacturing contrl tranwsmission fault code

1. What make/model/year vehicle?
2. Any other problems arising?
3. Have you scanned the OBD system for fault codes?

hi, dear friend, this is an obd2 trouble code tabkle, it can help you understand the meaning of code.
and this is tool can help you clear it.

Check your gas cap. I know this sounds dumb but that is usually what triggers an evap. malfunction

Please post the code that it gave you. But it sounds like you have a bad shift solenoid.

this code is in reference to a turbo fault code that comes up either with a weak turbo or internally leaking turbo / dragging turbo impeller /pintal shaft,
could also refer to a turbo waste gate vacumn contrl issue

Your code P1128 MAP Lower Than Expected one possible cause can be your manifold tempeture sensor

Had the same code on my 2002 Jeep Grand Cherokee. Started having shifting problems as well. Code is for governor pressure sensor on trans. Cost me about $800 for dealer to fix. No problems after part changed out.

P1494 Leak detection pump pressure or mechanical fault, hope this helps

the code refers to the crankshaft and camshaft sensors, the crank sensor has a higher failure rate, but usually the engine will not start or run when it does. the camshaft sensor can fail and the engine will still run. I would check the connections to each sensor for damage or corrosion, the system has lost signal from one of them, if you check them with an OHM meter they should not measure open

p1627 which is explained as
Manufacturer contrl.
Aux. inputs
Aux outputs

it means there's a problem on either aux input or the output try to check both connection.
