1999 S70 non turbo ETM questions
I've a 99 naturally aspirated volvo s70 with 109K miles. Currently the ETM light and check engine lights are on. It has very little power. If you give yourself some time it will eventually get to maybe 30-40mph. In park, the idle rhythmically surges between about 1100 rpm and about 1900 rpm. If you turn the ac on or put in gear, the idle does not surge but goes to around 1900. When driving, pushing the accelerator has little to no effect.
A bit of history: the problem did not present itself all at once but got progressively worse over time and about the last 10K miles. Now it is constant. If I recall correctly, the etm light didn't come on until the problem got bad.
I've done a little bit of google searching and suspect I need to send the etm to xemodex for rebuild but am not sure. I purchased a code scanner and multimeter this morning on the way to work.
The sticker on the bottom of the etm is white.
Thoughts/suggestions?

Thanks guys. I'll look into the ARD kit as well.
I pulled codes with an innova 3040 scanner. The codes were:
P1026 (x2)
P1032 (x2)
P1053 (x2)
P1057 (x2)
P0722 output shaft speed sensor circuit no signal
P1021
No definitions for the codes other than the one listed on the scanner.
I erased the codes via scanner. two copies of P1026 and one of P1032 and P1053 remained. The ETS light went of. I cranked it up and drove it a block. All of the codes returned. It still ran poorly. The ETS light did not come back on but it may take multiple key cycles.
Do these numbers tell you anything?

I looked up the definition for the other codes at the innova site.
P1053 vvt control circuit bank 2 short circuit
p1032 af sensor heater circuit high bank 1 sensor 1
p1057 vvt control motor bank 1 supply voltage electric malfunction
p1026 intake manifold air control solenoid short to B+
p1021 injector cyl no. 2 shorting to ground
Are these what you would expect associated with the ETM?

So, the question is, why are some of the codes indicating a vvt issue? Does innova have the wrong definitions for the codes?
Suggestions?

I'm showing that 1999 non-turbo denso models do not use a vvt solenoid on either cam - only on 2000 models

Finally getting back to this... Took the ETM off. I had to take the starter bracket off due to the size of the plug. Got my arms nice and cut up.
Anyway the flap in the ETM is really notchy feeling when you open/close it and it doesn't necessarily spring itself back closed. Is this an indicator of a bad ETM?
