ADJUST THE TPS SENSOR SIGNAL TO 1.0-1.25 VOLTS THROTTLE CLOSED (U MUST USE A DIGITAL VOLT METER, THEY ARE AVAIL AT RADIO SHACK FOR ABOUT $10 FOR A VERY BASIC DVOM), NEVER SET SENSOR CLOSED THROTTLE VOLTAGE TO < 1.0 VOLT, DO THIS WITH THE KEY ON AND ENGINE OFF, THERE ARE THREE WIRES TO THE TPS, SENSOR SIGNAL, GROUND, REFERENCE VOLTAGE, I DON'T HAVE THE ACTUAL WIRE COLORS BUT HERE IS WHAT U DO, ATTACH THE SENSOR AND PROBE THE THREE WIRES WHILE YOU MOVE THE SENSOR WITH THE VOLT METER, YOU WILL SEE THAT ONE OF THE WIRES HAS A VARYING VOLTAGE FROM <1 VOLT TO ABOUT 4 VOLTS AS YOU TURN THE SENSOR, AS I STATED ABOVE ONCE U DETERMINE THE CORRECT SIGNAL WIRE FROM THE TPS ADJUST IT TO 1.0-1.25 VOLTS, NEVER <1 VOLT. ONCE THAT IS DONE TIGHTEN THE SENSOR DOWN AND RECHECK THE VOLTAGE SIGNAL, IT CAN CHANGE, MAKE MORE ADJUSTMENTS IF NECESSARY.

No spark 92 volvo 240 with B230F engine. One single spark when ignition is turned off. Thanks


Your model has a timing belt Part cost about $50 depending on the a store. Check it out by looking at TOP DEAD CENTER marks from camshaft and Crankshaft with the position of Piston # 1 at the top while both exhaust and intake valve are closed. When it is bad, timing is out of sequence causing this problem. Good luck.

How do I adjust the idle on my 1993 24 DL Volvo?


Trace the throttle cable from the accelerator pedal to the engine block , it will terminate in a lever

Somewhere on the backside of that lever is a screw which you can screw in to set the idle speed

It may not be a sensor, might be in the connector at thr sensor, or somewhere in the harness.
Check the connections at the throttle position sensor, and the idle air control valve/sensor.

1988 Volvo 240 DL won't start B230F


I had more or less the same problem. It would only happen when the engine was cold. According to the mechanic, the fuel pump was going bad. After replacing it, I havent had it happen to me again, granted its only been a couple of days since I changed it.
