hprice is right. when you get this code it's usually because the little "fingers" that slide against the metal potentiometer bar on the fuel guage sensor has gone bad or broken off, or in some cases just pushed away from the slider due to it's natural wiggling.

that sensor is located in the fuel pump and you can't really buy a replacement sensor so instead you get the new fuel pump.

I went to 3 yards for this car and almost all the rodeo's of this year had the fuel tanks removed and the fuel pump / sensor pulled. so you can save a hassle and just buy a new pump.

removal is tricky because you've got bolted to the tank the lines that go up, so you have to be careful about removing them. Plus getting that back into the tank is tricky as it has to be exactly straight up / down then the ring clips it down.

It was a long job but had to be done to get past inspection because the check engine light can fail inspections. even if it has nothing to do with smog.

What is code reader compared to scanner what does each one do

Code reader just reads codes. Won't give you live data. Only a scan tool can do that. But you can read the codes of a 1990 vehicle with just a paper clip and counting the check engine light flashes. Very little live data was available back in 1990. Buying a scan tool for that car would be a waste of money.

No...the fuel sending unit is not a computer driven item nor is it monitored in any way by the onboard computer system. Interface with scanner and retrieve code(s) associated with indicator lamp occurrance

The car starts and runs fine, but the engine warning light is on all the time, plus there is a display that reads Motor System- Service required, what might be the problem? Its a 2002 Volvo S60

you need scanner to read codes. The old days we had to guess from experience but these days if the light is on or you feel a driveability issue most of the time a code will be in the computer memory. This is the fisrt step. With a code we will be able to help

If P1627 is set when there is a problem with the fuel level sending unit, 100% sure on this problem, replace the fuel level sender in the gas tank, about 2.5 hours, very straight forward job

Smog test will not pass

This code is send (in your case NOT SEND)
by the fuel sending unit.

Does your fuel gauge give incorrect of jumpy reading when it's full?

The quick fix is STOP TOPPING OFF the fuel tank when you are get gas.

Keep topping off will push the fuel tank float off it's sensor limit and eventually short or send OUT OF RANGE reading to the fuel gauge.

Fill your truck up to 3/4 tank full.

Drive it for 2-3 days or about 100 miles.
(this will fill the ready-ness data that DMV want)

If there is NO check engine light ON during the 2-3 days then give the smog test another shot.

DO NOT add fuel unit you complete the smog test.

The CORRECT method to fix your problem is to drop the gas tank and replace the fuel sending unit.

If you truck has over 140,000 miles on it then I will recommend you the change the WHOLE integrated fuel pump/fuel sending unit and fuel filter at the same time.

p1627: [driver "1" input high voltage]...

I believe the PCM was expecting a signal from a sensor (which one I don't know) that should be low voltage and instead was high voltage and therefore triggered a DTC for that sensor...I will guess a bad O2 sensor...

code may also be cleared by disconnecting battery negative wire for 30 seconds...remember to reset your clock and radio settings...

sorry that is all I can find...please rate me solved
