Well, I FINALLY found code P210E on the 2009 Service Manual CD (personally, I think the 2008 CD is poorly laid out)...just as EZ 2b says...BUT...the diagnostics are complex for this "P210E-Throttle Position Sensor 1/2 Correlation-Bank 2".
"...One trip fault and the code will set within 5 seconds. ETC light will flash."
"Possible Causes:
Excessive Resistance in the (K928) TP 2 Signal 1 Circuit.
Excessive Resistance in the (K929) TP 2 Signal 2 Circuit.
Excessive Resistance in the (K921) TP 2 Sensor Ground Circuit.
Excessive Resistance in the (F856) 5-Volt Supply Circuit.
Throttle Body.
Powertrain Control Module (PCM)."
I realize that this may be useless now, but, it does give you SOME notion as what they may say at the dealer.
I am a firm believer that these "limp modes" do correlate to color batches within a given year.
Just for YOUR peace of mind, the 2008 CD says same thing
Good luck, and please let us know outcome.
