Reduced engine power

[Camaro2ss2010]

Best bet is to find someone that can read live data. It can also be caused by a short in the wiring harness. One of the common spots is on the left side of the engine bay just below the head. It tends to be rub into the metal clamp holding the harness in place. I would be willing to bet there are more codes than just an O2.

I'm having the reduced power issue. I've replaced pedal and TPS inside the TB. I'm running a fast lsx 102 intake and BBK 102mm TB. It's very intermittent though. It's done it once in about a month. Before that 2+ months. Code thrown today was p2101. Any luck on fixing it?

I had a similar issue after installing a Soler Ported TB. It threw P2101 and P1516 (they are related). According to HP Tuners member forums, you have to reinstall the stock TB or adjust the tolerances (%) for the 2101 and 1516 channels by using their software. I have HP Tuners software and have access to these channels. I will tweak the % and see if it keeps me out of REP. In the meantime, I put my stock TB back on. These are your only options. There is no other solution unless you purchase a stand-alone ECM and custom software.

Oil pressure was reading correctly again. Took off and within 1 minute it said reduced engine power again but the oil pressure read correct. I have a 2010 SS with the LS3. It has the list of mods in my signature. Haven’t taken it to get the codes read yet as I am waiting on the performance shop to call me back that built it less than two months ago. Any ideas on what could cause it.

We have a 2010 SS that has the same message on the DIC. The PCV valve failed causing the engine to flood with oil where it wasn't supposed to be. That was just part of the problem. We also have a 5-volt reference to ground on the oil pressure switch. Now... the switch has been replaced, but the message still shows on the DIC after a few miles. The oil pressure switch was disconnected and the problem went away. There seems to be a short to ground on the oil pressure switch. Now to find someone who won't charge an arm and a leg to fix it. Good luck!
