  1. Change the wiper blade that clears the sensor to a sligthly longer one. This worked for me.
  2. Just remove the "Dome fuse" wait 30 sec and re-insert fuse. This resets the buzzer.
  3. The D in D4 stands for Direct injection. This means the fuel is injected directly into the cylinder chamber during the compression stroke. This means the fuel/air ratio can be varied depending on load of the engine. The D4 can under certain (rare) circumstances run with a fuel/air ratio as lean as 1:40 which in theory should give a low fuel consumption.
  4. Only vehicles with electrical power steering are affected. For the Avensis this is only valid for the 1.8 L.
  5. Avensis 2003 is ISO compliant. I have an ISO cable and it works great on my Avensis.
  6. The 2001 Avensis 1AZ-FSE does not have a MAF. the 2003 Avensis with 1AZ-FSE have MAF sensor.
  7. Breaking news !!! You can stop trying to find your MAF because the MK1 (and Mk 2 I think) with the 2L D4 engine does not have a MAF sensor. Instead it senses the vacuum in the intake manifold in order to calculate the intake air volume. This is refered to as a "D-Type" injection. The latest Avensis with the same engine does have a MAF as well as the manifold vacuum sensor. This is refered to as "L-Type" injection. The 1.8 l VVTi engine does all have a MAF sensor.
  8. The 1.8 VVTi (engine code 1ZZ-FE) I think has used the Iridium plug from when it was first introduced. Other Toyota engines with distributorless ignition also probably use Iridium plugs. They are expensive but last for long and with excellent performance.
  9. They would be expensive since they are probably double platinum or even worse Iridium electrodes. You must consider these modern spark plugs runs with much wider gap since the electronic ignition generates much higher voltage than the old distributor type ignition. If they are Iridium type the electrodes are also much narrower in diameter, almost as small as a fine pencil tip. In any case I think the Iridium plugs last about 15 000 miles before they need replacing.
  10. Your highlighted area is far away from the air filter box. Too the right in Pic 1, what is the connector for below the "RELAY & FUSE" box? I bet that is your MAF. :)
  11. Then your Avensis must be different than mine (and others). Can you post a picture of your air temperature sensor?
  12. Your MAF is in the Air filter box. The MAF and Air temperature sensor is integrated in the same device. It is held wit two screws in the box.
  13. Just as I thought The error code P0171 is generic and you can check the explanation of it here P0171 This code relates to a parameter that adjusts the fuel injection timing to compensate for wear and other changes in the engine over time. This compensation is normal but eventually this parameter value goes out of range and the ECU set the P0171 code and lights the MIL (check engine light on dash). The other code mentioned P1174 confuse me. It is not a generic code so it may be a Toyota specific code but I doubt that. It could be that the tech. has read the code wrongly and it should be P0174 instead which is the same as P0171 but for cylinder bank 2. But this confuses me even more unless you have an Avensis with a V4, V6 or V8 engine. The straight four cylinder engine only has one bank. Still I doubt the oxygen sensor but rather suspects the MAF (Mass Air Flow) sensor. This is common and what happens is that the sensor may get dirty over time and the sensor can not perform as intended. Therefore it is worth checking this and have the MAF cleaned. Inside the sensor there are wires of platinum that are heated with electrical current and over time deposit from the intake air tends to build up on the wires. You can clean it yourself or have a garage do it for you. Of course you can also change the MAF but this is probably very expensive. Cleaning it only cost you a can of electronic cleaning spray and an hour spent doing the job. Do a google search on Cleaning MAF sensor. This link for instance is for Lexus with an excellent description and will be very similar to how to do it on your Avensis Link Good Luck
  14. My Avensis have heated leather. I guess Toyota dare not sell a car in chilly Sweden without heated seats. I think SAAB was the first car to offer heated seats as standard so they must have set the standard in Sweden. My cruise control do not overshoot as far as I noticed. I use my cruise at least 80% of my driving, even in town. Even worse, no provision for playing MP3 music I have noticed that the manual seat goes a bit lower than the electrical. I guess it is the motors and electrical crap required under the seat that prevent it from going lower. Comes with HID headlights since it is required by law Again, required by law if you have HID headlights. Now on this I must agree with you. Absolutely useless. And even if it was correct in its calcluations, I hate it when it reset every time you fuel the car. On my previous corolla it had to be reset manually. This meant you could decide if you wanted it to calculate for a specific distance, per month, per year etc. Same goes for the average speed. It resets every time you turn the ignition on. Why not let the the driver decide how to measure the average speed?
