These are the common symptoms of a defective Volvo Electronic Throttle
Module, ETM, ETS.
- ETS light turns on
- Check Engine light turns on
- Loss of power, you step on the gas
pedal and the engine will not accelerate

mode, you can only partially accelerate to about 30 MPH
- After losing power, you turn the
engine off, start it again and everything appears normal
- Engine stalls

- Make sure you have had the recall done
on the ETM

and not binding
The cost to repair your ETM unit
is $300.00 plus $25.00 US Priority Mail shipping to return the unit back to
you. The repair cost is $325.00 US. Shipping is for the US. No
international shipping is available for this unit.
Removal and installation of your unit is available for $80.00 for NA and
$120.00 for turbo models. This is in addition to the repair. Obviously, this
is for local customers in the Los Angeles, CA area. We service Los Angeles
area, San Gabriel Valley, Inland Empire and Orange County; however, we get
customers from out of state very often.
I provide repair services for Volvo ETM units and ABS
control units. The units are also known as
modules and or computer.
My service costs about 1/3 of the price of a new Volvo ETM unit.
The ETM unit will be properly cleaned to ensure the air flow and
throttle plate is not binding or restricted, the unit will be repaired with
the new contactless throttle positions sensors and you will NOT need to download new software to
get the unit to work. The repaired unit has one year warranty, same as what
you get at the dealer.
I have been providing my services to independent Volvo dealers,
independent Volvo repair shops, Volvo clubs and Volvo owners worldwide for
over 9 years. I have been a member of the Volvo community since 1987.
You must know this information:
- There is a recall for the ETM, you
must have the recall done before attempting the repair of your ETM. Call
your dealer and ask them if there are any recall pending for your Volvo.
You may also be told that your ETM needs to be cleaned. Cleaning of the
ETM is a maintenance task that should be performed every 50,000 miles to
ensure the throttle plate is not binding or restricting the air flow.
- Even though a software update is not
necessary, it is advisable to get the latest software installed on your
Volvo, it corrects a few issues that were in need of correction.
- There was a class action lawsuit in
which Volvo agreed to extend the warranty of the ETM to 10 years or
200,000 miles. All 1999 Volvos are out of warranty now and the 2000 models
are expiring now. If you have a 2000 Volvo, check with your dealer to make
sure you are no longer covered by the warranty.
- I cannot troubleshoot your problem
over the phone or emails. If you send me your ETM, you must ensure that
your problem is the ETM. You are responsible for performing the
troubleshooting, this requires that you educate yourself on the symptoms,
reading and investigating the meaning of DTC (diagnostic trouble codes),
know how to use an OBDII scanner.
- The CEL (Check Engine Light) in your
instrument panel is an indicator of an emissions system problem. It could
turn on due to a defective ETM, a defective ABS unit, leak in the fuel
evaporative system, misfiring in the cylinders, defective sensor(s), worn out
O2 (Oxygen) sensor or just by fueling your car while the engine is running
or not tightening the gas cap tightly. If you send me your ETM and your
CEL is on, you will need to read the DTC and write them down. After the
repaired unit is re-installed, you will need to erase the codes. If the
CEL turns on again you will need to perform troubleshooting to determine
what other problems you have, the ETM was not the only problem you had.
- Some of the ETMs have mechanical problems and
the throttle plate is binding and/or stuck. Those units cannot be
repaired. You will need to purchase a complete unit including a $100
core deposit. On this units, when you start the engine, the idle speed
starts between 2,500 and 3,000 RPM, and then the engine starts misfiring
and the idle drops to about 900 RPM with severe engine misfiring.
