Fault codes back

[bertman]

A few weeks back had fault codes 515 camshaft position sensor and the code 553,basically the Maf,both occur at the same time.both have been changed,put a new sensor in and a new maf,now the same codes have reappeared.

anything else can cause these two codes to come back after new parts fitted??

I would try unplugging the ECU and spraying both the ECU and the plug with contact cleaner as these connections can become dry over time.
If this doesnt resolve things i would use a multi-meter to check the continuity of the wires between Maf/Cam sensor plugs and the ECU.

With these blooming cars it could be anything,will clean the contacts in the morn and see what happens.

Anyone else know what could cause these codes to return after the parts in question were replaced with new items???????
