P1443 - EVAP Emissions System Purge Solenoid Valve Circuit
1. Check the EVAP purge solenoid valve for proper operation.
- The valve should open and close when power is applied and removed.
- If the valve is not working properly, replace it.
2. Check the EVAP purge solenoid valve vacuum hose for leaks or blockages.
- If the hose is damaged or blocked, replace it.
P0340 - Camshaft Position Sensor Circuit Malfunction (Bank 1)
1. Check the camshaft position sensor for proper operation.
- The sensor should send a signal to the PCM indicating the position of the camshaft.
- If the sensor is not working properly, replace it.
2. Check the camshaft position sensor wiring for damage or corrosion.
- If the wiring is damaged or corroded, repair or replace it.
P1151 - O2 Sensor Circuit High Voltage (Bank 2, Sensor 1)
1. Check the oxygen sensor for proper operation.
- The sensor should send a signal to the PCM indicating the oxygen content in the exhaust gas.
- If the sensor is not working properly, replace it.
2. Check the oxygen sensor wiring for damage or corrosion.
- If the wiring is damaged or corroded, repair or replace it.
3. Check the exhaust gas for leaks.
- An exhaust gas leak can cause the oxygen sensor to read incorrectly.
- If there is a leak, repair it.
