is this the timing belt going or is it something elts

THANKS

Not the belt. If it goes you'll know.

Does your check engine light ever come on?

[lovmysvx]

yea but it does not stay on

sometimes it flash on then goes off

the longest it has stayed on was like 15 sec

[Earthworm]

I would recommend checking codes. Instructions are in the SVXipedia on http://svx-iw.com

[lovmysvx]

cant tell what code it is because the light has only come on 3 times in the last month

[SubaSteevo]

If you follow the instructions for checking error codes the computer will tell you all of the saved codes as well, you CE light does not need to be on to read them.

all right thanks ill look harder

[lovmysvx]

ok thanks ill try doin that tomarrow
let you guys know

[lovmysvx]

it was puting out code 23(air flow sensor), and code 38(engine torque control,wiring haeness between ecu and tcu is in a short circuit)

What should i look for/do about these codes

thanks for the help so far

[lovmysvx]

sorry went and checked again and it was code 22(knock sensor 1 RH),and code 37(O2 sensor 2 LH)
does that sound more like the cause of my problem?

if so then all i have to do is replace both sensors and im good right?

[Earthworm]

There are procedures for testing the sensors themselves. The error doesn't necessarily mean the sensor is bad but could mean it's reading values out of range.

[lovmysvx]

OK.. making more sence.

how/what should should i check for
or what could cause ( if the sensor is not bad) the sensor to throw the code?

[Earthworm]

I don't have the service manuals so I can't tell you which wires to check, what you're checking (volts, ohms, amps) or what values to expect.

Hopefully someone else jumps in right about now

[lovmysvx]

Thanks for all your help.

ill check them and let you know how it turns out
