How to solve the p2 135 fault code?

The failure causes of p2 135 of Pacific Auto Network include the failure of ETC throttle position (TP) sensor circuit or connector, the failure of TP sensor itself, and the failure of electronic control module (PCM or ECM). Solution: firstly, eliminate the connection problem between the plug of throttle body position sensor and the wiring harness; Make sure the line connection is reliable. If the fault cannot be eliminated, replace the throttle position sensor; If replacing the throttle position sensor still doesn't work, try to replace the newly obtained throttle body.

Throttle is a controllable valve that controls air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and the combustion is successful. It connects the air filter and the engine block, and is called the throat of the automobile engine. If there is too much sludge in the throttle, it may cause poor engine acceleration and increase fuel consumption.

First, apply a little oil on the fixed metal beam ring to avoid slipping teeth during disassembly. Remove the metal wire harness ring of the throttle hose. After the hose is removed, the left end is the position of the throttle. Remove the negative battery, turn off the ignition switch, straighten the throttle plate, spray a small amount of "carburetor cleaner" into the throttle, and then carefully scrub it with polyester rag or high-spin "non-woven fabric". Deep in the throttle, you can clamp the rag and scrub it carefully where you can't reach it.

When cleaning the throttle valve, it is not necessary to disassemble it, but the sealing part of the inlet steam must be cleaned, and the idle motor must be disassembled to clean it. After cleaning, follow the disassembly procedure just now. Don't forget to initialize the throttle after installation.
