[SIR Philbutt]

As above on 03 estate

Had the dreaded P1555 code for a while. Have swapped cam sensor, throttle body and checked breathers even tried Lambas must be the MAF although car runs fine

Please reply or PM with costs

TIA

Thats not a MAF code

[SIR Philbutt]

From the maintenance guide
P1555   Throttle Position Sensor (TPS) Load Signal not Plausible with Engine Load

The Autel i'm using (and some web lookup's) says this after setting it as a Vauxhall
Throttle Position sensor/Mass Air Flow sensor – Implausible Signal

After all that i have done the MAF is only thing left

What would you suggest Bigtime? although this is not the right section perhaps PM

On my 2.2 i had these codes.

P0170 (2) lean exhaust-not present
p1555 (0) throttle position sensor (tps) load signal not plausable with engine load-not present
p0340 (4) camshaft position sensor circuit no signal-not present
p1700 (0) svs via can-not present
p0335 (8 ) crankshaft sensor incorrect signal-not present

After fitting new GM cam sensor, I had these codes.

P1555 - Throttle Position Sensor (TPS) Load Signal not Plausible with Engine Load  - Not present
P0170 - Lean Exhaust - Not present

After doing the TPS and breather guide exactly how the guide says I had no more codes..

[SIR Philbutt]

So, as I said, done that, been there, no alternative, need to see if it's the MAF - Thanks for the info

Still want one, Anyone out there got one ?

Have you tried Steve at Omega spare parts? If no one on here has one might be with giving him a bell

I had issues on my 2.2 and after trying the 'known good' route only a new VX MAF fixed the problem - I'm not sure if they all start to fail with miles?

They are not expensive from VX with TC.
