1998 saturn sl cam posiner sincer po341 a ckt rng/performe bnk1

It means that the O2 sensor isn't switching as fast as it should. Make sure there are no vacuum or exhaust leaks. Most Likely you got a lazy O2 sensors which would require replacement.

both codes refer to Crankshaft position sensor A code 339 is CKT Intermittent and 341 is CKT Range Performance. you may have to replace the sensor.

It basicall means you got that camshaft a little bit out of sync.If it a twin cam or a singke overhead cam what it relates to is the position in relation to the crank both have sensors the crank moves the pistons up and down and the cam opens and closes the valves and in that car drives the distrubitor . So the spark along with the opening and closing of the valves is to early or to late. I know you dont eant to but remove the timing belt covers and turn the crank to TDC ( top dead center) look at your cam timing marks ill bet they aren't exactly where they should be. Line those up and erase those trouble codes and reset the check engine light youll be good to go

157= 02 sensor ckt low volts 2/ 2 158=o2 sensot ckt high volts 2/ 2 159= o2s ckt slow response 2/2 181= fuel temp sensor a ckt rng/perform 327= knock sensor 1 ckt low imput bank 1 or single sensor 332= knock sensor 2 ckt low input bank 2

CODE PO113 - INTAKE AIR TEMPERATURE SENSOR INPUT ABOVE MAXIMUM ACCEPTABLE RANGE. CODE PO133 - UPSTREAM OXYGEN SENSOR RESPONSE SLOWER THAN MINIMUM REQUIRED SWITCHING FREQUENCY. CODE PO341 - CMP SENSOR SIGNAL RANGE PERFORMANCE CONDITIONS. POSSIBLE CAUSE COULD BE CAMSHAFT POSITION SENSOR FAULTY OR PCM FAULTY GOT TOO MANY CODES. LET DEALERSHIP CHECK IT OUT USING DIAGNOSTIC EQUIPMENT. YOU DONT WONT TO BUY ALL THOSE SENSORS IF PROBLEM ELSE WHERE THE COST WILL ADD UP THAT WHY LET DEALERSHIP CHECK IT OUT.COULD BE THE PCM OR SHORT IN WIRING.

Replace what ever the codes say needs replaced,,,start with the ERG,,,Than run the scan again, if that engine oil switch comes up after you replace the ERG than replace it. Always clear the codes after you read them.

CODE PO133 IS HO2S - 11 BANK 1 SENSOR 1 SLOW RESPONSE CONDITIONS. POSSIBLE CAUSES THE EXHAUST LEAK PRESENT IN THE EXHAUST MANIFOLD OR PIPES.FUEL SYSTEM IS TOO RICH.FUEL PRESSURE TOO HIGH FUEL PRESSURE REGULATOR LEAKING OR ONE OR MORE FUEL INJECTORS.STICKING LEAKING.HO2S ELEMENT IS SILICON WATER OR FUEL CONTAMINATED OR IT FAILED.TP SENSOR ELEMENT BROKEN.CAN CAUSE FALSE ACCELERATION EVENT.OR THE PCM HAS FAILED.

well code 133 is a oxygen sensor fault....new one runs around 60-100 dollars.

The 341 code I have no info on...most likely related to the O2 sensor.

Good Luck

Hello DTC P0341 & P0133 very common saturn Codes.You need to check condition of Plugs & wires,If not New Replace All Plugs & Wires,also I would replace the #1#4 Coil for the P0341.For the P0133 Reaplce your front O2 sensor with an OEM sensor,not an aftermarket.
