| Question: |
92 mits eclipse gs, 2.0L, non-turbo, m/t. just bought car, had been sitting a year,timing belt was broke. I repaired head ,replaced all belts,spark plugs good..it seems to be firing ok.Double checked the timing, ok. But car runs rough,engine cuts out at 4G also check engine light comes on goes out after returns to idle. I checked codes and got a 22 code, which book says its a crank shaft sensor problem. performed poinpoint test on crank shaft sensor,the book says to replace sensor. could there be any thing else that could set this code? The part cost 250.00, I want to check everything before spending that much if it's not that. thanks for your time. |
| Answer: | Duane, If the timing belt is off a few notches, then that can cause the check engine light (CEL) to come on and throw that code. But you mentioned you thoroughly checked your timing, so it's probably not that. Before you shell out any money for a new CKS, check your car's computer.
Read this article for further information: If your ECU is manfunctioning, it can cause such problems as RPM cut
and for certain sensors to show faulty readings. But if you do need to
get another crankshaft position sensor, call around to auto salvage yards
or even check eBay for used sensors. You'll get a much better deal. Any
Eclipse, Talon, or Laser made between 92-94, 2.0L, non-turbo should would
work. |
