what I have encountered in the past is the ABS module was the cause. what happens is the wire connections become loose and fail to make proper contact, causing the brake,abs, and speedo to stop for short or long periods of time.if equiped with a tach it also will jump from 0 to 1500 or other places. I have noticed that the other components such as speed sensor,abs plugs, or instrument panels does not make all of the above things do this all at once. like I said this has been my findings and only suggesting a hopeful fix for your issue. best of luck to all.
On All Newer Toyota vehicles, the tachometer receives it's information directly from the ECU, or on board computer. This is a bit of a sticky problem, however, I would first disconnect the negative side of the battery cable from the battery and check and clean the electrical connection at the back of the instrument cluster in which the Tachometer is housed. and then I would check the connections to the ECU. If I recall, it is behind the glove box on most Toyotas. The after that I would reconnect the battery cable and test to see if it solves the problem. Have you read the error codes stored in the ECU? That might also give clues as to where the problem is originating.
Most manuals recommend checking every 50k and replacement at 150k. If it breaks while the engine is running, especially on the road, the repair cost 4 times as much because it will most likely damage the valves and the piston heads. The Haynes and Chiltons repair manuals, both are good and available, can explain replacement and checking methods. I use the timing checks as a guide for checking the Belt/chain. If your timing is bouncing all over the place your belt/chain is probably stretched or the device meant to keep tension on it is not working properly. Some vehicles with Timing belts as opposed to chains have a tensioner built in to maintain the proper tension on the timing belt. That are also a few vehicle that employ this with a timing chain.
Use a Screwdriver to LOOP the HOOD LATCH "CABLE" AROUND and BOUNCE your FIST ON the CENTER of HOOD WHILE SONEONE IS PULLING on The CABLE WORKS EVERY TIME FOR ME ! PB Blaster Sprayed LIBERALY on the LATCH ASSMBLY Always Works to Free it Up After. BE SURE the CABLE is PROPERLY MOUNTED UNDER the HOOD If NOT DO SO Or REPLACE ENTIRE CABLE
The most likely problem is that you need a new voltage regulator put in the alternator,the tach runs off of it and when the tach quits i think you will find that the car also stops charging,the brushes for the alternator are in the regulator and a new one usually fixes the problem.
Possible speed sensor. I know the speed sensors are a problem with hondas. A new speed sensor is about $200 and can be easily replaced. It bolts to the top of the transmission on the firewall side. Do NOT buy an e-bay one. They are only about $30 but are junk
sounds like a bad bulb. the filament in the bulb will bounce around and reconnect its self sometimes. when it is out tap the lens with your finger tips if it illuminates replace the bulb and recheck. the problem may lay elsewhere, but this is a cheap easy place to start.
