Hi,
The codes are related to the throttle position actuators. When the P2135 is set, a message indicator should indicate, Reduced Engine Power.
Check the connectors at the throttle body. Make sure nothing is damaged or shorted, and make sure the connector pins are in good condition and not corroded.
I attached the diagnostics below for the P2135. This is where I would start simply because it deals with an open circuit, and the other code shows a variation in voltages between throttle position sensors 1 and 2.
Take a look through the diagnostics (which also includes48
a description) and let me know if you are comfortable performing them.
Take care,
Joe
