Apologies for this being a bit long but looking for suggestions that I have not already done
As above - have been getting this error when spanner light comes on, although light not on permanently, it resets with ignition off/restart.
P1555 Throttle Position Sensor (TPS) Load Signal not Plausible with Engine Load
Happens when cold and hot, town and motorway, petrol and LPG.
The only occasion I can make it happen consistently is when parked up and holding the revs between 1500 - 2500, occurs almost instantly.
The car drives normally, at all times.
Revs do not fluctuate when idling.
Fuel consumption seems usual
When started cold the revs are 1100ish and come down to 800ish after a couple of minutes
Have researched on here and t'internet and consensus is clean throttle body & unblock hole and breather pipes - did this, no fix
Other suggestions include,
replace throttle body & gasket - done that
replace cam sensor - done that
replace lamba's - done that
have also,
replaced MAF and air filter.
EGR blanked and un-blanked
I am getting desperate and trying anything
Some history, in done order, to fix numerous other problems
New Silencer - padding blown out
New CAT flexi - blowing
New CAT back boxes - rusted
New EGR gasket - leaking
New exhaust manifold - cracked
Cannot recall when code first appeared but was definitely there when I was investigating the EGR gasket problem
Did suspect throttle, but discounted it when discovered the error occurred when using cruise control
Also have considered ECU, but assumed I would be getting other problems as well
Completely stuck now can anyone suggest where to look now
?
TIA
Phil
so going to replace both and considering upgrading to a stronger spring as she is often loaded up especially when going on holiday (no not with a tin tent).
