How much of an issue is the steering sensor within the PSM.
Leading evidence: 'steering sensor within the psm' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'steering sensor within the psm' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Adjust (which i need' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

So I will have the camber/tracking work done and the recalibration can be checked when it next goes for service to either the OPC or an Indy.

Mine is a MY03 PSM fitted C2 Tip Coupe and I know that the O/S front castor angle needs some adjustment as does the front tracking on both sides - albeit all very minor adjustments.

The car is only used for road driving and not tracked.

However your unequivocal answer is contrary to that in Adrian Streather's book - 996 Essential Companion - Page 303 - viz - 'WARNING - The Steering Angle Sensor must be re-calibrated if the previous wheel alignment values for any 996 model fitted with PSM have ben changed'.

Upshot is that their considered opinion is that the sensor would need re-calibrating if some of the steering gear had been replaced, however for slight geometry adjustments it was not so essential.
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.

Have just had front tyres renewed (Pirellis). Tyre Fitter had latest laser tracking alignment rig and a check was free so had the car checked. I knew there was some problem as the front O/S tyre was wearing on the inside edge. The alignment check showed that the front O/S wheel camber was slightly out of tolerance as was the tracking on both fronts. Problem - If I have the tracking adjusted (which I need to) the tyre place does not have a PS2 to recalibrate the steering sensor. As I live in the depths of Cornwall the nearest OPC at Exeter is some distance away.
How much of an issue is the steering sensor within the PSM. The car is only used for road driving and not tracked. Will it make that much difference to everyday use?
All advice appreciated
Richard - many thanks. However your unequivocal answer is contrary to that in Adrian Streather's book - 996 Essential Companion - Page 303 - viz - 'WARNING - The Steering Angle Sensor must be re-calibrated if the previous wheel alignment values for any 996 model fitted with PSM have ben changed'. Mine is a MY03 PSM fitted C2 Tip Coupe and I know that the O/S front castor angle needs some adjustment as does the front tracking on both sides - albeit all very minor adjustments. Mighht it be that for very small adjustments then your statement still holds good which will save me a lengthy trip up to Exeter when I can get the alignment done locally?
Richard - done as you suggested and they were very helpful. Upshot is that their considered opinion is that the sensor would need re-calibrating if some of the steering gear had been replaced, however for slight geometry adjustments it was not so essential. So I will have the camber/tracking work done and the recalibration can be checked when it next goes for service to either the OPC or an Indy. Many thanks
Just to add to this,Was about to have new tyres fitted and geo done,Anyway o/s rear camber bolt had rounded itself so geo couldn't be done so they put it back as best they could
so I could drive to opc Exeter to pick up new bolts and washers,one of there staff did explain that after every geo the system should be re-calibrated otherwise psm and abs failures could occur.
On my way back to protyre PSM and ABS failures did occur.
I think small adjustments is OK as I have mine done every 3-4 months, because our roads are so bad
Basically do have it re-calibrated every so often
