SOURCE: Code p0335 ckp sen/circuit appears as fault.

Try disconnecting the battery for several minutes and reconnecting. This will usually reset any alarms/fault codes.

SOURCE: ocv circuit in toyota

OCV is the oil control valve for the VVTi system, it's located on the side of the cylinder head at the front and has an electrical connector on it, the valve may the problem but it cou;ld also be a clogged oil passage that supplies regulating pressure to the valve or the VVTi gear, the system operation can be checked by connecting an intelligent tester that can activate the system to verify if the valve is the problem, before replacing expensive parts I would make sure what the problem actually may be.

How to change a 2002 toyota brevis settings to english plz help


Hi Zachary, sorry I haven't been able to find anything helpful for you. The only thing I did discover is the following extract from Wikipedia "The Toyota Brevis is a mid-sized luxury sedan introduced in May 2001 and sold only in Japan" this being the case it may need a firmware change from a Toyota dealer. Good luck in your quest, sorry I couldn't have helped.

We understand that your problem is: We have a 1997 GMC Safari 4.3 Litre 2 wheel drive. Stalls when idleing. Sputters when accelerating at speeds around 70-90 kms. Gas consumption has risen dramatically....


Welcome to the world of improper diagnostics. There isn't a trouble code in the world that says you should replace a part. It only tells you what's going on with that component. In your case, the code P0137 means that the computer sees Low Voltage on the Bank I Sensor 2 oxygen sensor. You replaced the sensor and still have the problem. That means the computer sees Low Voltage on the Bank I Sensor 2 oxygen sensor. In other words, you've got a wiring problem, not a part problem. You'll need a shop manual with step by step instructions on how to test the entire circuit to find the fault.

Air Conditioner for Benz 1998 E320


Check system for codes;

Displaying & Reading Trouble Codes (DTC Memory)
Air Conditioning (A/C) 

Models 208 as of MY 1998

Diagnostic trouble Code Memory [15] 

Note: 
  • The A/C pushbutton control module (N22) has DTC memory and data output. The diagnostic trouble codes and data are displayed via the temperature display window. The stored DTC's will remain in memory even with the vehicle battery disconnected.
  • The DTC memory differentiates between current and intermittent faults.
  • Numerous DTC's can also be read with the Hand-Held Tester (HHT).

Preparations for DTC Readout 

  1. Review 11, 12, 13, 14, 15, 21, 22, 31, 31, 41
  2. Ignition: ON
  3. Temperature selector: left: "HI"; right: "LO"
  4. Ignition: OFF
  5. Ignition: ON
  6. Within 20 seconds press REST and EC simultaneously for more than 5 seconds.
  7. The LED in Recirculated Air flashes and the display shows "d1A".
  8. Press AUTO repeatedly until all DTC's are displayed. Record each DTC as it is displayed.
  9. Each fault (short circuit, open circuit) is assigned a DTC. Thus in the left display: "E1" appears, and the right display indicates the DTC. The current faults (refer to table) are displayed first, next, the intermittant failures (e.g. 45 °5) are displayed in the display window next to the FAN symbol. By pressing the right AUTO the next DTC is displayed.
  10. To erase: Can only be performed after all faults have been readout. Press left AUTO and right AUTO buttons simultaneously for more than 2 seconds and the display shows: left: "d" and right: "FF". To cancel erase: By pressing the left AUTO button, the current faults will appear again.
  11. Select a base temperature setting.
  12. Turn ignition OFF, to end test.
Note: Due to instrument cluster (IC) series interface, DTC's may be stored in IC memory, therefore readout and erase DTC's from IC memory.
