    Gear shifting check

    Dear Experts with my all the respect, In my car ( carina at 192) I feel like torque is not delivered when needed. In a road with inclination upward I feel the car is less torque and raising more than it should be ( i.e. it raises around 2 - 2.5k) and changes to a gear which is also seems less power. I checked how to test whether the gears are shifted properly and did following test based on my car manual. 1) get a voltmeter connected to TT (+ve) and E(-ve) in diag socket. 2) get the reading while I am driving. 3) The voltage values at different gear positions are in attached pic below. 4) Problem is when I drive I only (even in flat or inclined roads) get 0v, 2.1v, 4.1v and 6.1v. I could not obtain higher value than 6.1v since I did not test it in a highway. 5) For an example at gear upshift 0v -> 2.1v -> 4.1v -> 6.1v. 6) My problem is, as per below table I should get some voltage near 1v as well since its the second gear. This value is hardly given when I drive very slowly ( <10kmph). But Other times I am not getting the second gear. Is it normal? Cant the car get shifted to second gear if i need more torque in a hill ? PS - the letter B in the picture is for letter V. (Volts).

    RPM vs speed

    Hi, Thanks for the valuable input.. infact in my datasheet there is a method of checking the gear position using voltmeter ( since my car is OBD I port). Next time I will check this and let you know which gear engaged exactly at 100kmphs. Please see the attached pic below on how to check it.

    RPM vs speed

    Hi, Is the gear at 3rd position at 100kmph normal? If I calculated as if it should be in 4th gear it gives RPM of around 2000 at 100kmph, which has never been achived by my car yet..

    Door ventilator

    Hi All, In my car rear door, there is grilled area for ventilation purpose ( see picture 1). Originally it shall be fixed with a valve like window panel.(See picture 2). Currently I am not having that thing in both rear doors. What is the purpose of this particular thing?

    RPM vs speed

    Hi all, In a flat road or highway for my car which is a 1.5 engine, rpm is between 1800- 2000 when going at 70kmph. When I go 100kmph it is at 2700-2900. Is it normal? My car is Carina AT 192 , 5A-FE engine and A245E gear box. Thanks..

    Idle Air Control Valve Issue

    Will check nd let u know..

    Idle Air Control Valve Issue

    PCV checked no issue with it.... also its a new one..
  8. Dear Experts with my all the respect, I am really messed with this IAC valve thing. My car has rotery solenoid valve as IAC. RSC coil for closing side and RSO for opening side. ECU provides a PWM to one and inverted to the other. (i.e. If RSO gets PWM with 75% duty cycle, RSC gets its inverted PWM which is 25%. This makes a resultant force to IAC open 50%.) My data sheet gives the RSC and RSO values attached herewith. Please see picture 1.You can see resultant of IAC is at idling with no AC, is "closed". But when I check it in my car, the resultant of IAC at idling with no AC is, "opened". Please see picture 2 & 3. Picture 2 is RSO. Picture 3 is RSC. ( eventhough it should give inverted to each other please disregard it since it's an issue with oscilloscope.i.e. time shift does not shown by oscilloscope.) 1) I checked for vacuume leaks and none found. 2) I also checked these RSC, RSO values at different throttle adjusting screw setting. No change. 3) Checked IAC with values in datasheet and it was OKAY. 4) Also I checked idling speed which is at around 750 rpm. 5) Also I checked rpm when AC switched on which is increased from 750 to around 900. Pic 1 - first two graphs are RSO and RSC without AC. Pic 2 - RSC without AC Pic 3 - RSO without AC What is the issue in my car? Why can't I get the setup in the datasheet?

  10. Nop.. It was early morning in cold state. I mean not running. After I post this, I had a run around 40 mins and checked engine off after that on parking. Same level ( 1 cm above upper HOT line) no change.
  11. Hi guys, I recently did an auto transmission fluid change. When I checked the level early in the morning the fluid level shows around 1 cm above HOT upper cut level. I mean there are HOT upper and lower cut within which the lvel should be when hot and COLD upper and lower within which fluid lvel when cold. 1) Is there excess amount of oil? 2) Do I need to drain ? 3) My auto is working well but it gets a lil bit delay to chang into gears ( I dunno weather it is a normal thing because I am always expecting no time interval between any two gear ). Might this because of this excess fluid?

    AC Cabin Filter

    Does it hv a local outlet?

    AC Cabin Filter

    Hi All, I was totally dissapointed to hear almost all the so called "AC repairers" do not know that there is a cabin filter in toyota cars like corolla, carina and corona in 90s. My car is 96 one which is not having a filter in the compartment and i am searching this filter. Still I was unable to find in panchikawatta and several other places. In internet this item is available. Anyone who knows local place to get it? At least to order ? Toyota PN : 88508-20020 ( upper filter) 88508-20030( lower filter) Sakura eqvlnt: CA11070

    RPM at Drive position

    As per my car manual idle should be within 650 to 750. No issue in TPS, MAP and ECU. Have to check for vaccum leaks... any idea on how to check ? Since O2 sensor adjusts when there is a vaccum leak it is very difficult to find it from rpm.
  15. Hi Guys, My idle rpm at position N or P is around 725. When I apply D position when vehicle is in stationary, rpm drops to 500 ( I do not feel considerable vibration).. Is it normal? Or should it be increased? All above are AC/Head lights etc in off condition.
