Where is the speed senor located in my van? and also, the knock senor.

One in each bank. Knock senor 1 and knock sensor 2.

No a knock sensor can not make a misfire. Check the coils, plugs and fuel pressure .The random misfires are cause the knock sensor to throw the code.

try looking on the hub. located near the brake caliper. on the front of the vehicle.

1. Raise and safely support the vehicle.
2. Remove the tire to ease access to the knock sensor.
3. Remove knock sensor shield
4. Remove the connector from the knock sensor.
5. Remove the sensor mounting bolt,
6. Now remove the knock senor.
7. To install reverse the steps above and tighten the bolt to 18 pounds torque.
8. See diagrams for additional help. Note there is one on each side of the engine.

• Hope this helps and thank you for using FixYa.

The Cam Position Sensor is a common item to fail. However, the cam positioning mechanism can fail too giving that code.

There are two sensors and the Exhaust Cam Sensor is most common to fail. I always replace both.
Te CKP's are on the top front of the engine next to the cylindrical operation solenoids.

Knock sensors fail too and need checked or correct feedback to ECU with a scanner.

These engines require regular oil changes with quality synthetic oils and OE filter....not a FRAM or WIX !

Buy only BMW sensors ...aftermarket have high failure rate.

If the speed sensor is for an Anti-lock braking issue, you will normally find 1 at each wheel (accessible when the wheel is removed). Another location would be on the transmission.

U may have a bad knock senor

Hi...
If the speed sensor Not work on a Automatic Transmission.
The over drive will not work.
The over drive is a SENSOR Located inside of the Transmission.
On vehicles with 3.0 liters.
On vehicles with 3.3 0r 3.8 liters, Is Part of the selenoid pack.
But if you have a 3.3 or 3.8 Liters.
Most cases the transmission will not go up shifting.
it will Stay on 1st or 3r.

If your van is a 3.0 liter , I will recomend replace the speed sensor.
Located At Right side of the Trans. on the firewall side.

if you have 3.3 or 3.8 liters.
I recomend replace the Input and Output shaft Speed sensor.
Located at left side of the Transmission. Behind the Selenoid Pack.

The first step I recomend Is get the Vehicle scaned with a Diagnostic scan tool.
To know exactly what is the problem.
Is there some autoparts That do scan on vehicles with no charge
Just a Complementary service.
Advance autoparts, Autozone autoparts, Pepboy's Autoparts.
And some Napa Autoparts.

OK. I hope this help on your problem.
Thank you for use fixya....
