  1. Problem Reports
    So I had a code on my 2006 mitsubishi eclipse gs 2.4 L 4 cylinder. Where it said Catalytic converter warm up efficiency was bad. I was told it could be one of a few things. The MAF sensor (I replaced it, and made no change) the catalytic converter was bad, or that it was the downstream oxygen...

    So that some of you will benefit from my experience. I needed to change my upstream, driver's side oxygen sensor. I went to RockAuto and ordered a Bosch 15582 oxygen sensor. In the description for this part, it says that the wires from the sensor to the plug is 18.1". After removing the old...
  3. Problem Reports
    I recently got the dreaded engine light and got the code read at a local O'reilly's. The code stated P0051 Oxygen sensor heater control circuit low Bank 2 sensor 1. Which sensor is involved? And is it only the sensor that could cause this or something else?
  4. Problem Reports
    Hello everyone, I own a 2007 Mitsubishi Eclipse GT and I've had the dreaded O2 sensor codes for as long as I can remember. Just the past weekend, I decided to gut out my pre-cats and install O2 spacers for the oxygen sensors (All 4). I was hoping that the codes would finally disappear but sadly...

  6. Eclipse Performance
    Anyone have any luck with O2 sensor simulators. Need to pass inspection, but don't have the $1200 to dish out for a manifold cat just yet. Looking for a temp fix to get passed.

  8. Tuning and Electronics
    Hey guys! So I recently started to tune myself using Fastworks on my laptop. Up until now I've been on Hackish' tunes he sent me with maybe small changes but am finally diving into ignition timing and fuel. Also change mivec to 3200 which I love. Anyways, I need a wide band but dont want to...
  9. Problem Reports
    okay so about a month ago my engine light popped on in my car. I just took it to autozone to run the diagnostics on it and it said i had a bunch of Oxygen Sensor Heater errors. I'll list them out: •U1108 Combination Meter Timeout • P0031 Cylinder 1 , 4 Heated Oxygen Sensor Heater (Front)...
  10. New Members Forum
    Hello guys today I got my check engine light on went to autozone and gave me a code P0431 (Bank 2 warm up catalyst efficiency was below treshold (cylinder 2, 3) for a predetermined period of time). They say it could be the catalytic converter or a heated oxygen sensor. I've been reading many...
  11. 4G Eclipse GT/SE Specific
    P0037 and P0051 codes will not go away, inspection is due!! Ok guys, i have searched this forum and i am still confused on these damn Oxygen Sensors. My CEL is on due to P0037 and P0051 P0037 is for my Bank 1 Sensor 2---Heater circuit low P0051 is for my Bank 2 Sensor 1---Heater circuit low...

    hi, everyone!! I have a mitsubishi eclipse 2002 gt 3.0L v6 automatic . recently i noticed that my car is high on RPM when the engine is not warmed up(the temparature is about 70F), the RPM is about 1600 at idling when i start up the car, then after about 5 minutes of driving, it goes...
  13. Problem Reports
    I have 3 codes running I know what all three are for, to mention I did just break an 02 sensor hitting a curb but I have had this issue since I bought the car a year ago. p0157 cyl 2, 3 heated oxygen sensor(rear) Low Voltage p0037 cyl 1, 4 heated oxygen sensor Heater (rear) Control Circuit Low...
  14. 2006-2012 Eclipse (General 4G)
    I have noticed a pattern on these and other forums. People think a CAI or new filter will improve MPG. This is false and to confirm it myself I read a very extensive case study I will have to link later (its nearly 6am and Ive had some wine) Your ECU will regulate the gasoline sent to the...
  15. 2006-2012 Eclipse (General 4G)
    whats going on guys, hope everything is well. I have a 07 eclipse gt with the 3.8 and for some reason the car would not start today. im not sure if its because the rear oxygen sensor is not in at the moment, or because of anything else. bought a new battery and it tries to start but it doesn't...
  16. Problem Reports
    Have had both these codes show up since I bought the car. P0051 is Bank 2 Sensor 1 oxygen sensor. I have had the O2 sensor replaced but the code still shows. However, my gas mileage noticably increased so that shows that the sensor should be working properly. (The code does not show until the...
  17. Problem Reports
    Hi, I just finished gutting the cats on the front and rear manifolds, the job itself was harder than anticipated, especially if you do it at home. My problem is that I could not remove the rear bottom oxygen sensor to install the anti-foulers, I know this is needed to prevent the check engine...
  18. Problem Reports
    I got dreaded P0037 code, but with the strange twist. The light will come on ~2-3 seconds after I turn the engine on. If I clear the code and start the engine again everything is fine and light won't come on while driving, but will reappear if restart the engine. Engine seems to be running OK...
  19. 2006-2012 Eclipse (General 4G)
    I've got a CEL the codes are P0421 and P0431... P0421 says: Warm up catalyst efficiency below threshold-Cylinders 1-4 P0431 says: Warm up catalyst efficiency below threshold-Cylinders 2-3 Probable causes: Faulty Catalytic converter, Exhaust leak near heated oxygen sensor, Faulty rear heated...

    I have an '06 eclipse GS with the 2.4. replaced all oxygen sensors- cat converters and gas cap. but the check eng light still comes on and is the same 3 codes-P0158(twice) and P2253. Any one ever had this problem??? Am at a loss with it. Bought it used and the light was on than. Dealer said he'd...
