Yeah, I had a dealer put regular oil in my Camry when I gave them Royal Purple with a special additive. Problem for them is that RP is not honey amber in color; Purple durheh. The paid for new oil.

There is too much data to post here. PM me w/ your e-mail address and I will send a copy to you.

DESCRIPTION
HINT:
These DTCs relate to the Throttle Position (TP) sensor.
The Throttle Position (TP) sensor is mounted on the throttle body, and detects the opening angle of the throttle valve. This sensor is a non-contact type, and uses Hall-effect elements, in order to yield accurate signals, even in extreme driving conditions, such as at high speeds as well as very low speeds. The TP sensor has 2 sensor circuits. One circuit sends the VTA1 signal. The other circuit sends the VTA2 signal. VTA1 is used to detect the throttle valve angle and VTA2 is used to detect malfunctions in VTA1. The sensor signal voltages vary between 0 V and 5 V in proportion to the throttle valve opening angle, and are transmitted to the VTA terminals of the ECM. As the valve closes, the sensor output voltage decreases and as the valve opens, the sensor outputvoltage increases. The ECM calculates the throttle valve opening angle according to these signals and controls the throttle actuator in response to driver inputs. These signals are also used in calculations such as air-fuel ratio correction, power increase correction and fuel-cut control.
