Table of signs of malfunction (Honda CR-V 2)

If any of the above symptoms are present, check the vehicle's diagnostic trouble code (DTC) using a scanner. If the DTC is not present, perform the symptom diagnostic procedure in the order given until the cause is identified.

Sign of malfunction	Diagnostic procedure	Also check
The engine does not start (mIL lamp goes out, DTC codes are not written to memory).	1. Perform a battery test. 2. Test the starter. 3. Troubleshoot the fuel pump circuit.	Low compression. There is no ignition spark. Air intake leak. The engine is blocked. The timing belt is slipping/broken. Low quality fuel.
The engine does not start (mIL lamp comes on and stays on, or does not come on at all, DTC codes are not written to memory).	Perform troubleshooting of the MIL lamp circuit.
The engine does not start (immobilizer indicator is on or flashing).	Perform troubleshooting on the immobilizer system.
Difficulty starting (mIL lamp goes out, DTC codes are not written to memory).	1. Perform a battery test. 2. Check the fuel pressure.	Low compression. Air intake leak. Low quality fuel. Weak ignition spark.
Fast idle speed too low when not warmed up (mIL lamp goes out, DTC codes are not written to memory).	Check the idle speed.
Too high idle speed when not warmed up (mIL lamp goes out, DTC codes are not written to memory).	1. Check the idle speed. 2. Check/adjust the throttle cable. 3. Check and test the throttle body.
Unstable idle speed. (mIL lamp goes out, DTC codes are not written to memory).	1. Check the idle speed. 2. Check/adjust the throttle cable. 3. Check and test the throttle body.	Air intake leak.
After warming up, idle speed is below normal without load (mIL lamp goes out, DTC codes are not written to memory).	1. Troubleshoot the ALTFR signal target. 2. Check and test the throttle body.	The vacuum hose is clogged/cracked/not connected tightly.
After warming up, idle speed is higher than normal without load*1 (mIL lamp goes out, DTC codes are not written to memory).	Perform troubleshooting on the ALT FR signal circuit.
After warming up, the idle speed drops when turning the steering wheel. (mIL lamp goes out, DTC codes are not written to memory).	1. Troubleshoot the PSP switch signal circuit. 2. Check and test the throttle body.	Power steering system.
Unstable idle speed. (mIL lamp goes out, DTC codes are not written to memory).	1. Check the fuel pressure. 2. Check the injectors. 3. Troubleshoot the ALT FR signal circuit. 4. Check and test the PCV valve.	Low quality fuel.
Misfires or uneven RPMs (mIL lamp goes out, DTC codes are not written to memory).	1. Check the spark plugs. 2. Check the fuel pressure. 3. Check the injectors. 4. Troubleshoot the fuel pump circuit.	Low compression. Valve clearances. Low quality fuel.
Failed emissions test*2 (mIL lamp goes out, DTC codes are not written to memory).	1. Check the three-way catalytic converter (TWC). 2. Check the spark plugs. 3. Check the fuel pressure. 4. Check the injectors. 5. Check the Fuel Vapor Capture Carbon Filter (EVAP) purge system.	Low quality fuel. Low compression. The timing belt is slipping/broken.
Low power (mIL lamp goes out, DTC codes are not written to memory).	1. Check the fuel pressure. 2. Check the air cleaner filter element. 3. Check/adjust the throttle cable. 4. Check and test the throttle body. 5. Check the three-way catalytic converter (TWC).2 6. Check the injectors.2	Low quality fuel. Low compression. Valve timing. Engine oil level.
The engine stalls (mIL lamp goes out, DTC codes are not written to memory).	1. Check the fuel pressure. 2. Check the idle speed. 3. Troubleshoot the brake pedal position switch signal circuit. 4. Check the spark plugs.*2	Air intake leak. The wiring and connections of the sensor are faulty.
