1994 Volvo 850 Turbo Change the ECU with A Non Turbo ECU Parts
When the ecu of my 1994 Volvo 850 Turbo was showing some bad readings about the knock sensors, I picked and pulled the old ecu and got a new ecu from a 1993 volvo 850 non turbo. Is it possible for an ECU from a turbo car to replace ecu from a non turbo car? Thanks.
Answer: No. The turbo creates a significant change, since the engine compression is changed significantly. VVT
A/F Ratio
Wastegate control
Banked injection
Would be different or missing from the ECU. The knock sensor sends signals when the A/F mixture pre-detonates before it can be ignited by the spark plug, and the computer corrects it with VVT. You need to buy the correct ECU.

1997 Toyota Camry 2 2 L How to Replace the Serpentine Belt On 1997 Toyota Camry 2 2 L
How can I replace the Serpentine Belt on my 1997 Toyota Camry 2.2 L 4 Cylinder?
Answer: Toyota Camry equipped with power steering has two belts. One that operates between the crankshaft pulley and power steering pump. The other is drive belt that operates from the crankshaft pulley to the alternator and air conditioning compressor. To replace the large diameter belt that drives the alternator, you have to remove the plastic shield in front of the crankshaft pulley (held in place by two 10mm bolts). The pivot bolt on top of the alternator is loosened (14mm), the bolt that secures the front ear of the alternator (12mm) is slackened and then a long threaded adjusting bolt (12mm) is turned to loosen the drive belt so it can be removed and replaced. It is more difficult to replace the power steering belt since it is accessed from the bottom of the car so the car must be jacked up and supported by axle stands. A bolt on the power steering pump adjusting bracket and the pivot bolt for the power steering pump must be slackened to enable the power steering belt to be replaced. After replacing the fan belts assemble in reverse order. Ensure fan belts are properly tensioned and aligned. Start the engine and allow to run for a minute. Re check alignment and drivebelt tension. Turn on air conditioning, headlights, heated rear windscreen and start the engine, turn the steering wheel form side to side, if belts are properly tensioned the belts should not “squealâ€. If belt “squeal†is heard the fan belts are improperly tensioned or aligned.
