this is a drive by wire no throttle cable correct ?
what is the AP sensor 1 and AP sensor 2 and AP sensor 3 reading at rest with your foot off the gas pedal with the ignition key on?
thats correct no throttle cable. I notice with just the engine cranked in park it's idling at anywhere from 1200-1800 rpm then it will occasionally drop into the normal 700-900 range. The TP monitor reads 0% at this time, strange since i would think it would read at about 10% or so.
I will try after I leave work today. I dont know if my reader has that capability I have the Actron reader. Is this a common problem you have addressed before?
we have seen bad connectors and connections at either the gas pedal assembly the throttle body, bad throttle body's and bad gas pedal assemblies
if you follow this it will lead you to the problem
DTC P1125 ETC (Electric throttle control) Limit Performance Mode
The acceleration pedal angle will vary about 13 % at idle position to about 87 % at wide open throttle (WOT). This code detects if the system is in Limit Performance Mode and Multiple DTC Performance Mode. (Fail safe Mode)Conditions for setting the DTC
Action Taken When the DTC Sets
Conditions for Clearing the MIL/DTC
Diagnostic Aids An intermittent may be caused by the following:
A change in the display will indicate the location of the fault.If DTC P1125 cannot be duplicated,the information included in the Failure Records data can be useful in determined vehicle mileage since the DTC was last set. If it is determined that the DTC occurs intermittently,performing the DTC P1125 Diagnostic Chart may isolate the cause of the fault.
Thanks I will be trying all of these this afternoon and possibly in the morning. I will let you know how it all turns out. Thanks for the very detailed information.
you can always get me back through this post with any follow up any time with this problem even after you rate us here at Justanswer!
On my lunch break went out and checked the Rodeo.. here is what the ODB II code reader is putting out.. I don't think this reader that has AP1 AP2 or AP2 capabilities.
ABSOLUTE TPS- 0% (idling @ 1100-1250)
ENGINE ADVANCE- 110
FUEL SYSTEM 1- OPEN2/CLOSED
FUEL SYSTEM 2- OPEN2/CLOSED
O2 ST11- 0.05
O2 ST21- 0.375
O2 ST22- 0.36
When the gas pedal is pushed all the way to the floor the Absolute TPS percent only gets up to 42% and the RPM is only around 4200
Ok, we ordered the APS since that was the only thing that was giving up intermittent reading on the voltage..It will be here on or before Wednesday. I will let you know if that finally corrects the problem.
