Trouble code P1507 means: Idle air control (IAC) underspeed error
Check engine is an error. You have to go at a garage to see what is the error code, then correct the problem.
If there is an AutoZone close by you can go there and they will pull the computer codes for free. If not, you'll have to visit a repair shop with the ability to do so; they typically charge for this.
With a scan tool.
If you have an OBD (On Board Diagnostics) scanner, you can read the error code and reset check engine light. Obviously, if the problem is still occurring the light will come back on. Most of the chain autoparts places will read and reset the OBD for you for free. the scanner read #141
The computer doesn't allow to start the engine. Check the error code.
You need to check your engine. The computer has detected a problem with the engine management system and the light is letting you know that is has error codes stored.
check your engine
Pretty simple connect an obd2 scanner and it will pull the error codes for the check engine light then look up the error code and diagnose and fix your problem
ANY error code in the computer.
That means an error code has been set in the ECU memory. You need to have the codes read with a OBDII scanner, then look up the reference codes in a manual in the engine controls section. A good scanner will tell you what the codes are. Mine was a loose O2 connector.
Some of hoses will make for sure the check engine light come on. It depends on the house. If you are sure that it was the hose reset the computer and check your assumption. If you have access to an error code reader check the error code, it might simplify your life.
