17834/P1426/005158 - EVAP Purge Valve (N80): Open Circuit

Possible Symptoms

• Malfunction Indicator Ligh (MIL) active

Possible Causes

• EVAP Purge Valve (N80) faulty
• Wiring/Connectors from/to EVAP Purge Valve (N80) faulty
• Fuel Pump Relay (J17) faulty

Possible Solutions

• Check EVAP Purge Valve (N80)
• Check Wiring/Connectors from/to EVAP Purge Valve (N80)
• Check Fuel Pump Relay (J17)

16487/P0103/000259 - Mass Air Flow (MAF) (G70): Signal too High

Possible Symptoms

• Probably no serious malfunctions
• Loss of power

Possible Causes

• Wiring and/or connections (short circuit?)
• Mass Air Flow (MAF) (G70) defective

Possible Solutions

• Check wiring and connections
• Check / Replace Mass Air Flow (MAF) (G70)

Check continuity of the EVAP solenoid, if that's okay then you need to check that there is a feed to the solenoid. Also check whether there are any breaks in the wiring to the solenoid.

The MAF code will require a logging session to asses how much air the engine is ingesting/thinks it's ingesting.

but i have replaced the maf for a new bosch one

 

[ex911driver]

did you delete the previous codes? and re scan again?

 

[Lewis583]

That doesn't mean it's any good though. New parts can be faulty too. Logging/diagnosing is required as just replacing parts willy nilly can get expensive.

If you are adamant the new MAF is good, then you need to start tracing back wiring checking for breaks, high resistance at plugs etc

Agreed with Lewis, heard a lot of people taking MAFs back because they are faulty..

will get it exchanged tommorow and fault codes were deleted last time
