By a built-in sensor unit, the manifold absolute pressure sensor detects the intake manifold pressure as a voltage. The ECM then determines the basic injection duration and basic injection advance angle based on this voltage. Since the manifold absolute pressure sensor does not use the atmospheric pressure as a criterion, but senses the absolute pressure inside the intake manifold (the pressure in proportion to the present absolute vacuum 0), it is not influenced by fluctuations in the atmospheric pressure due to high altitude and other factors. This permits it to control the air-fuel ratio at the proper lever under all conditions.

A thermistor built into the engine coolant temperature sensor changes the resistance value according to the engine coolant temperature. The structure of the sensor and connection to the ECM is the same as in the intake air temp. circuit malfunction shown on page DI-26 . If the ECM detects the DTC P0115, it operates the fail-safe function in which the engine coolant temp. is assumed to be 80°C (176°F).
HINT: After confirming DTC P0115 use the OBD II scan tool or TOYOTA hand-held tester to confirm the engine coolant temperature from ”CURRENT DATA”.

The tire pressure warning system informs the driver if it detects a low tire pressure. When the tire pressure warning system detects low tire pressure in any of the 4 wheels which affects safe driving, the tire pressure warning light comes on. Tire pressure warning system is controlled by the Brake Actuator Assembly (skid control ECU). When the tire pressure reset switch is pushed, the tire pressure warning light goes off.

Valve Body Inspection
1. If a line-to-lube hole has been drilled in the PR valve circuit, it should be plugged to reduce converter drainback.
2. Inspect the TV checkball separator plate seat. Leakage here may produce stacked shifts and/or no kickdown.

Disassembly Instructions
1. Remove the detent assembly & spring retainer bracket, see Figure 1.
2. Remove the original pressure regulator spring and valve.
3. Remove the end plate on the opposite side of the bore and remove the line/TVpressure plug and sleeve assembly and the spring.
4. Keep the OEM line/TV pressure plug spring and the end plate. Discard all other OEM components.
5. Clean the bore thoroughly in a solvent tank.

In late 1995, six months after Toyota decided to move forward with its revolutionary hybrid, the Prius, and two years before the car was supposed to go into production in Japan, the engineers working on the project had a problem. A big problem. The first prototypes wouldn’t start. “On the computer the hybrid power system worked very well,” says Satoshi Ogiso, the team’s chief power train engineer. “But simulation is different from seeing if the actual part can work.” It took Ogiso and his team more than a month to fix the software and electrical problems that kept the Prius stationary. Then, when they finally got it started, the car motored only a few hundred yards down the test track before coming to a stop.

Toyota’s Camry Solara coupe is all-new for 2004. This second-generation Solara was developed by the Toyota Technical
Center in Ann Arbor, Michigan, designed by the company’s Calty center in Newport Beach, California, and is built at a
Toyota plant in Kentucky. Its new look, which is both sportier and more elegant, is reminiscent of the Lexus SC430, most
noticeably in its flowing surfaces and rounded rear.
Two engines are available: a 157-hp, 2.4-liter four-cylinder and a new 3.3-liter V-6 that makes 225 horsepower and 240
lb-ft of torque-a gain of 27 hp and 28 lb-ft over the previous 3.0-liter V-6. The four has a standard five-speed manual
transmission or an optional four-speed automatic, while the six is coupled with a new five-speed automatic with a manual
