Technician A says that if the oil pressure reads low, the oil pressure sending unit should be replaced. Technician B says that if the oil pressure is low,the oil pressure should be measured using a separate pressure tester. Who is correct? Select one: a. Technician A b. Technician B c. Both A and B d. Neither A nor B

## Step 1<br />This problem is about diagnosing and addressing low oil pressure in an engine. The statements of Technician A and Technician B are both correct.<br /><br />## Step 2<br />Technician A suggests that if the oil pressure reads low, the oil pressure sending unit should be replaced. This is a correct statement because the oil pressure sending unit is responsible for transmitting the oil pressure reading to the gauge. If the unit is faulty, it can cause the gauge to read incorrectly, leading to a false indication of low oil pressure.<br /><br />## Step 3<br />Technician B suggests that if the oil pressure is low, it should be measured using a separate pressure tester. This is also a correct statement because a separate pressure tester can provide a more accurate reading of the oil pressure. This is because the pressure tester is not affected by any electrical issues that might be causing the gauge to read incorrectly.<br /><br />## Step 4<br />Therefore, both Technician A and Technician B are correct in their statements.
