cụ cho nổ máy rồi cụ rút jack kim phun máy 2 ra xem có hiện tượng gì khác k
xem nó có bỏ hẳn máy 2 không.
cụ tập trung xử lý, tìm nguyên nhân ở máy đấy thôi

Em có xe camrry bị lỗi p0202 em đã kt mobin buzi . Xúc kim . Rồi mà k đc cụ nào lm rồi chỉ em vs ạ em cảm ơn
Nói thật với bác là tài liệu xe này mình còn chưa có nữa, nhưng ở đây có cái này, bác đọc có hiểu không chứ mình đọc là mình làm được rồi đó!hihi Luôn tiện học tiếng anh bác!
*What does that mean?
P0202 means that the PCM detected a fault in the injector or the wiring to the injector. It monitors the injector and when the injector is activated, the PCM expects to see the voltage pulled "low" or close to zero. When the injector is switched off, the PCM expects to see a voltage that is close to battery voltage or "high". If it doesn't see the expected voltage the PCM will set this code. The PCM also monitors resitance in the circuit. If the resistance is excessively low or high it will set this code.
*Potential Symptoms
The symptoms for this code will likely be a misfire and a rough running engine. Poor acceleration. The MIL will also be illuminated.
*Causes
The causes of a P0202 engine light code could be any of the following: Bad injector. This is usually the cause of this code but doesn't rule out the possibility of one of the other causes Open in the wiring to the injector Short in the wiring to the injector Bad PCM
Possible Solutions
-First, using a DVOM check the resistance of the injector. If it isn't within specs, then replace the injector.
-Check for voltage at the fuel injector connector. It should have 10 volts or more.
-Visually check the connector for damage or broken wires.
-Visually check the injector for damage.
- If you have access to an injector tester, activate the injector and see if it operates. If the injector operates, then you likely have either an open in the wiring, or a blocked injector. If you do not have access to a tester, swap the injector with another one and see if the code changes. If the code changes, then change the injector.
-At the PCM, remove the driver wire from the PCM connector and Ground the wire. (Make sure you have the correct wire. If you're not sure, do not attempt) The injector should activate
-Replace the injector
