Rpm Meter Issue

carboy2011 · July 11, 2011

Hi I looked at a car and the RPM meter was not working,owner said RPM meter sensor is faulty my question is

i) is it difficult access it to repair it?

ii) where is the sensor located?

iii) cost and availability of sensor?

The car in question is a Mitsubishi Lancer C12 1300cc model (1985) hence will the part be available?

also is there a big difference between the Lancer GLX c12 1500 cc vs 1300 cc models? any known issue?

what is the current market price for it ?

The problem could be:

1) a faulty display in which case the solution involves checking the wiring - no problem.

2) No signal to the gauge - simple: trace the wire to the crankshaft, fix any loose connections, mechanic can do it easily.

3) Heat (maybe generated by the flywheel? Not sure) damages what your guy calls 'the sensor' (which is a misnomer if it is an older model analogue kit using the voltage pulses) over time. This is harder to repair, but not hard per se for a mechanic. It should require some parts. INstall another meter temporarily to see if the crankshaft speed rate readers are messed up. If they are, then parts are called for, if they are available or not, I have no idea, possibly you may be better off installing a new RPM meter - maybe a infra red laser one, but it may be quite dear.

Can't comment on the cars, sorry, but the metre is repairable and replacable, no worries.

I think you are considering whether to buy this vehicle. I would actually put it back to the seller and ask him to repair it himself if he suspects "the sensor". This problem is best posed to an auto electrician who would be able to guide you better.

Parts would probably be available since this was a popular car, and the difference between the 1300cc and 1500cc would be with AC on, the 1500cc would probably perform better both on fuel and engine pick up.

The most important thing to check in this car is corrosion as that would be the one that will put the biggest dent in your wallet.

There are more things to be concerned about, in a 25 year old car, than the RPM meter. I would say, if everything else is ok, go for it - especially the body condition. One of my friends had a C12 few years ago and it met with an accident. We had a really tough time looking for parts like the grille and the bonnet. Engine parts wouldn't be too hard to find though. It's got the omnipresent 4G13 engine.

Market price would also depend on the condition of the car, but I would guess in the range of 400k or slightly lower. Compared to C1x series Lancers, the box model Lancers seem to have held their market better.
