I suggest you get the car to a good mechanic who knows Lexus cars.

  • C1201 = Engine Control System Malfunction (VCS lamp ON-RX3) or ECM/TCM malfunction / 51
  • C1441 = ?(Code not listed so please recheck it).
  • P0300 = Random/multiple cylinder(s) - misfire detected.
  • P0302 = Cylinder 2 - misfire detected.
  • P0303 = Cylinder 3 - misfire detected.
The first one is a possible problem with the engine management system, (the car's brain). This could be a cheap or an expensive fix.
The last three are the cylinders not firing properly. It could be a problem with fuel or spark into those cylinders.

SOURCE: My 1999 lexus es300 is still reading the codes P0300, P0302,P0303 after giving it a tune up.

Your codes indicate misfires. What was done in the "tune up"? Misfires can be caused by any of several different causes including (but not limited to):
spark plugs
spark plug wires
coil packs
injectors
injector wires

The term "tune up" used to mean, "replace points, condenser, distributor cap and rotor, and plugs". Since most cars no longer have points, condenser, distributor cap and rotor, we need to ask what was done...

Fix code C1201


C1201 engine trouble code is about Crankshaft Position Sensor A Circuit Low Input.
The reason of C1201 OBD-II Engine Trouble Code is Manifold Absolute Pressure/Barometric Pressure Circuit High Input.
Parts or components should not be replaced with reference to only a C1201 DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.

A coil for most cars are normally not a very expensive part . Take a look on eBay for your type of vehicle for anidea if costings.
A coil is normally positioned in a placedwhichbis usually quite easy for a DIYer to fix themselves.
A Haynes manual or similar vehicle fixing manual may be worth while alternatively YouTube fixing it.
