1 matching discussions were examined; no attributable action/outcome evidence was detected. No consensus or repair conclusion is claimed.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.
3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.
0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.
0 acknowledgements have no verified action link; they do not establish a repair result.

The engine management light came on have had a EOBD diagnostic check and has come up with two fault codes P0453 Evaporative emmission system pressure sensor/switch high P0447 Evaporative emmission system vent control circuit open Just wondering if anyone can help i presume the two are linked if i get a new sensor i presume it will fix both i would like to know where the sensor is situated and if it is easy to locate. Many thanks 996carrera4s 2003
It might also be a wiring fault. This is what the diagnostic manual says about P0447 96 EVAP canister shutoff valve (output stage) - open circuit Diagnosis conditions * Engine running * Battery voltage greater than 7 V * Fuel tank ventilation active Possible fault cause * Wiring harness * Shutoff valve faulty * DME control module faulty The P0453 fault also indicates a wiring fault, as shown on the attachment. If you drop me an email I'll send you both sheets in full.
Sheets sent. There are a couple of threads here worth looking at: http://www.renntech.org/forums/index.php/topic/23862-p0453-tank-pressure-sensor/page__view__findpost__p__124564 http://www.renntech.org/forums/index.php/topic/27558-996-evap-canister/page__view__findpost__p__145494 Try searching there for P0447 and P0453 and you'll get lots of hits.
