Question about 1995 Toyota Camry

1 Answer

Engine management light is on, engine seems ok

I had a similar problem. Took it to Toyota agent found 2 problems. 1. the throttle position potentiometer was faulty. 2 the crankcase ventillation valve position potentiometer was faulty. They quoted approx $860 to fix. I went to the local library and read the workshop manual details. No.1 was fixed by carefully drilling a very small hole in the side of the sealed throttle position potentiometer and squirting a bit of RP7 lube/cleaner in the hole. This cleans the carbon surface of the potentiometer. Cover the hole with a bit of glue. I could not solve the other problem and went back to them. They tested it again and wanted to sell me another with a large aluminium casting attached for around $450. I went to Toyota spares and was able to purchase just a new pot for approx $50 (similar device in a hobby shop is around $1.75). which was very expensive for a device such as this. This did fix the problem. They charged me $20 for final test. All up, $70 was much better than $860. They will rip you off if you are not alert.
Am having trouble with reverse gear, very weak at first start in the morning, ok after that. No problems with all other gears.

Locate pcv valve.pulled throtle body nothing or valve covers


Crankcase ventilation system is used to consume crankcase vapors created during the combustion process instead of venting them to the atmosphere.
Fresh air is supplied through a filter to the crankcase, the crankcase mixes the fresh air with the blow-by gases and then passed through a positive crankcase ventilation (PCV) orificed tube into the intake manifold.
The PCV orificed tube restricts the flow rate of the blow-by gases using a 3 mm (0.118 in) (a) orifice located at the end of the tube. If abnormal operating conditions arise, the system is designed to allow excessive amounts of blow-by gases to back flow through the crankcase vent tube into the throttle body in order to be consumed by normal combustion. Positive Crankcase Ventilation Hose/Pipe/Tube Replacement
Remove the two nuts (2) from the fuel injector sight shield (1).
Lift the sight shield (1) from the front and pull forward to disengage the rear tab from the bracket.
Disconnect the PCV fresh air tube from the left camshaft cover.
Remove the PCV fresh air tube from the throttle body.
Remove the drive belt. Refer to Drive Belt Replacement .
Remove the power steering pump retaining bolt.
With the hoses still attached, Carefully position aside the power steering pump.
Remove the retaining clip securing the PCV dirty air tube.
Disconnect the PCV dirty air tube from the PCV orificed tube.
Remove the PCV dirty air tube from the intake manifold.

I have 99 bmw 323i.i ran it hot and got prob fixed and now the eml and a triangle with circle around it comes on dash and car has no power.feels like it has a rev limiter.wats wrong with my car


have throttle body checked also the MDK throttle motor,
make sure that the dealer has followed service bulletin 12 07 99 for procedure to replace the MDK throttle motor
also have them check for codes,here are some codes,
it could be an expensive job,have them check everything,it is most likely the throttle motor,,throttle body is 600 if they switch it,dont let them do it without checking throttle motor,

How do you get the pcv valve out of the valve cover


Usually you grasp it an pull it out.

Positive Crankcase Ventilation (PCV) Valve Removal & Installation To Remove:
PCV Valve location (3.3L & 3.8L engines shown, 2.4L similar) chry-04-33-829.gif

  1. Disconnect the vacuum hose from the positive crankcase ventilation (PVC) valve.
  2. Remove the positive crankcase ventilation valve from the valve cover.
To Install:
  1. Install the positive crankcase ventilation valve in the valve cover.
  2. Connect the vacuum hose to the positive crankcase ventilation valve.

I have Toyota Canina E 1992, it consumes 1L of fuel/ 9 kms and it is buderning for me, mecanicians failed to resolve a problem, what causes this and how can I get rid od it?


Hello! Is the engine in a high state of tune? Good plugs, wires, air cleaner...Does the engine perform correctly? Lack power, idle rough, hard starting? The throttle body air inlet is probably in need of cleaning,,,Carbon build up...Also inspect the air flow sensor...Dirty,fouled...etc....Replace the Positive Crankcase Ventilation (PCV) valve...If vacuum lines are soft and worn..Replace...After cleaning throttle body...Test the Throttle Positioning Sensor...See attached diagram...IDL=Pin#1...E1=Pin #2...And PWR=Pin #3...Meter probes to the TPS with connector removed...If TPS fails test it is the main problem...send a comment...Guru...Saailer1f50511.gif

Positive crankcase ventilation system


If built like most, the valve cover will have a fitting with a fairly large hose leading away from it.
The PCV valve (Positive Crankcase Ventilation) is found in this line.

This allows fumes forming within the engine oilways sometimes pushed out by minor blowby of the cylinders to be routed back to the air intake so they combust in the engine instead of being vented into the air, something we didn't worry about 50 years ago.
