Rev counter reading
I have a 1995 Nissan Almera 1600 GX auto petrol with engine GA16 DE. It has 73,000 miles on the clock. About a week ago, I was in heavy traffic and needed to get over to the right to take a right-hand turn at the next lights. I indicated right and floored the throttle, pulling into a gap. I glanced at the rev counter and the needle was up against the maximum stop. By then, I had feathered the throttle as I had all the speed I needed, the kickdown had operated as per usual and everything except the rev counter was fine. I got held at the lights and the needle stayed at the top no matter the throttle position and it was still stuck there when I returned home.
The following day, the rev counter went wild for the first mile or two, then it started to relate to the throttle position and over the next half-hour operated normally. Since then, on most days it always starts off wild and later calms down. I am sure that the needle responds to the throttle position as it calms down, which led me to think inlet track depression was involved as the response of the needle to throttle is instantaneous. However, as it improves, one realises that it is the RPM controlling the needle. Whatever the rev counter says, the engine always responds flawlessly to throttle. Ken Wilkinson The operation of the vehicle rev counter is electronic and driven by the information received from the ECU. Given that the engine performs correctly and the throttle response is good, the fault is most likely in the gauge itself. This is a known problem with the Almera rev counter and some owners have been successful in fixing it by removing the dash, stripping out the rev counter and resoldering the joints. This will take just a short touch with a hot soldering iron on each visible joint on the circuit board and will rectify the problem if it is due to a dry or cracked solder joint.
Before trying this, however, I would first check and ensure the connecting plugs are making a good contact with the dash and that none of the plugs are loose. A poor connection or bad earth may be to blame for the fault.
If the problem is more severe, a replacement rev counter will be needed.
