Reduced Engine Power

[ruffmanatv]

Ok, so I put a EGT gauge and a Boost gauge in my truck today. I have everything hooked up, except I forget to hook up the MAF sensor. I remeber this after I start the truck. Kicks a P0700 code, I get that cleared but it will not clear the Reduced Engine Power. I have taken the Tune back out. I cleaned the connection on the MAF sensor, and nothing seems to work. I unhooked the batteries for 15 mins also.

Any ideas on what it could be? Please help I am stuck driving a gasser.

p0700 is a a code in the ecm telling you that there is a code in the TCM.


your MAF sensor will not put you in reduced power mode.

Possible problem with your nsbu switch but you will need to pull the trans code.

Try flashing your stock TCM tune even if you are running a stock TCM tune.

Ok so he said it happened again. P2127, . I had MAF sensor off and nothing seems to be wrong with it. Not sure what it could be. It is not throwing the P0700 code anymore. Still getting reduced engine power too.

P2127 - Throttle/Pedal position sensor/switch "E" Circuit low input.....

check your fuses and check the wires that you tapped into for power for the gauges.


if the pedal is disconnected the truck will do this... maybe a broken wire or unplugged connector.. short... open... could be anything. just go over your wiring and fuses.

When friend was cutting the grommet to put boost tube and EGT wire through, he managed to cut one of the drive by wire, wires.:banging:
Got it patched up and is working good.

So thanks for all the help. Truck is up and running and gauges are working great.:beavisnbutthead:
