1. Place vehicle in a location where the floor is solid and flat, with adequate lighting. Do not attempt to work on a hot engine. Heat causes metal to expand and makes removal of fasteners difficult at best. Disconnect the battery cables from the battery. Raise the front of the vehicle to obtain adequate access to the bottom exhaust manifold flanges. Use large-base jack stands to support the vehicle. Do not rely on the jack! Block the tires to prevent the vehicle from rolling off the jack stands. 2. Spray WD-40 or some type of penetrating oil on all accessible fasteners and fittings before attempting to remove them. 3. From underneath the vehicle disconnect the exhaust system from the exhaust manifolds by unbolting the (3) bolts at the collectors. Then unbolt the driver side catalytic converter from the exhaust assembly and temporarily remove it from the vehicle. PASSENGER SIDE 4. On the passenger side remove the (4) bolts attaching the heat shields to the factory manifold. 5. Next, carefully unplug the O2 sensor from its harness. 6. Now remove the nuts attaching the factory manifold to the cylinder head. With the manifold out of the way remove the mounting studs from the cylinder head. 7. Using a small wire brush or similar instrument, clean any carbon deposits left on the head surface. Be careful not to gouge the aluminum head. 8. Transfer the O 2 sensor from the factory manifold to the new passenger side header. Apply a small amount of anti seize to the threads for the sensor before installing it in the new header. Use caution not to drop or damage the sensor, they are fragile. 9. Now you are going to install the new JBA Header, but first there is some preparation of the hardware required. Apply anti seize to the threads of the new fasteners. Install the new JBA Header using the supplied gasket and fasteners. Torque to 23 ft./lbs. DRIVER’S SIDE 10. Just like you did in step (4) remove the (4) bolts attaching the heat shields to the driver side factory mani- fold. 11. Next, carefully unplug the O2 sensor from its harness.

Time and Difficulty: I found the install to be moderately difficult and pretty time-consuming (about 3 hours) ; others have found it simple and report they have done it in as little as 30 minutes. Your experience will depend on your familiarity with the tools and electronics. I, personally, found insertion of the connection pin into the HV ECU plug to be difficult and almost got the first pin irrevocably stuck in the slot. I spent quite a bit of time with that part alone. I also found threading the wire behind the dash to be fairly tricky. I think the average person, not encountering any problems, could do this job in about 1-1½ hours. Procedure in Brief: 1) Remove bottom cover of steering wheel 2) Locate and unplug flasher plug 3) Open plug and remove 1-3 unused connector pins 4) Reattach steering wheel cover 5) Dismantle part of dash (vents) and remove lower glove box 6) Locate HV ECU (gray plugs) and remove lower plug 7) Solder wire to connector pin and insert into ECU plug (#27) 8) Splice EV button ground wire into ECU plug ground wire (#1) 9) Plug ECU plug back into the ECU 10) Thread wire behind dash to opening near dimmer switch 11) Attach switch to cover and solder wires in place 12) Reassemble the dash 13) Test Procedure in Detail: *Review ALL steps before proceeding and be sure you understand all terms used and you’ve looked at all diagrams and pictures. 1) Remove the bottom cover of the steering wheel by releasing the steering wheel adjustment handle and unscrewing the silver screw in that recess. 2004_prius_evv2.doc Page 4 of 20 Last updated March 13th, 2004 Then, turn the steering wheel 90 degrees right and remove the black screw that becomes visible on the right side of the steering column. Then turn the wheel 180 degrees left (90 degrees from normal position) and remove the black screw on the left side of the steering column. Carefully pull down on the lower portion of the steering column cover until it releases. Mine was a bit stiff/stuck to the upper part and you may need to carefully use a butter knife or screwdriver to start prying them apart. 2004_prius_evv2.doc Page 5 of 20 Last updated March 13th, 2004 2) Locate and unplug the white flasher plug visible just on the left side of the bottom of the steering column. 3) 2 little clips keep a cover locked in place. Pull those apart and remove the cover. Inside you’ll see lines of silver connector pins–some with wires attached, some without. You should remove between 1 and 3 of those pins–2 is probably safe, 3 might be better, since if you plan to install an OEM button at some point, you’ll probably need more pins for that. (You need one pin for the procedure, but it’s handy to have a back-up.) To remove the pins, you can use your paper clip to start the process of sliding them out, and then they just pull right out. 2004_prius_evv2.doc Page 6 of 20 Last updated March 13th, 2004 Stick them to a piece of tape or put them somewhere secure so you can find them later. Snap the cover back into place, and plug the flasher plug back in. 4) Replace the steering wheel cover by reversing the process. Be sure everything’s aligned properly and that there are no gaps. 5) Now you’ll need to dismantle part of the dash to get access to the ECU and other areas. First, open the top and bottom glove box doors. Squeeze the inside sides of the lower glove box together to get the catches past the portion of the dash frame that keeps the door from falling all the way open. Then pull the entire door straight toward you – it will unclip from the hinges at the bottom of the glove box. 2004_prius_evv2.doc Page 7 of 20 Last updated March 13th, 2004 You may also need to unclip the little hydraulic piston that keeps the door from falling open too quickly. Next, grasp the bottom of the silver vent piece next to the glove box. Pull it toward you firmly. It should unclip at the bottom first. Then pull the whole unit straight out

The PCV system is designed to prevent blow-by gas from escaping to the atmosphere by drawing it directly into the intake manifold. The PCV valve contains a spring-loaded plunger which is lifted in proportion to intake manifold vacuum. Under high vacuum, blow-by is returned directly to the manifold through the breather chamber and PCV valve with fresh air. When intake manifold vacuum decreases (wide open throttle) and vacuum in the air cleaner increases, the PCV valve closes and the blow-by is returned through the cylinder head cover breather hose and into the air cleaner. The PCV valve also acts as a check valve when the engine backfires to prevent crankcase explosion. Fig. 1: PCV system components-1984-87 1.5L engines Fig. 2: PCV system components-1988-91 1.6L engines Fig. 3: PCV system components-1992-95 engines Fig. 4: PCV system components-1984-87 carbureted engines SERVICE Positive Crankcase Ventilation (PCV) Valve For PCV valve removal, refer to Routine Maintenance of this information. 1. Locate the PCV valve. With the engine running at idle, use pliers to pinch the PCV hose between the valve and the intake manifold. It should be possible to hear the spring loaded valve click shut. 2. If no click is heard, remove the valve from the engine but leave it connected to the intake manifold. A hissing sound should be heard and vacuum should be felt at the valve inlet. 3. If no vacuum is felt, remove the valve from the intake manifold hose. The engine should stall or almost stall. This will indicate a stuck valve or clogged hose. Check the breather hose for clogging or leaks and replace any defective parts. Exhaust Gas Recirculation (EGR) System FUEL INJECTED ENGINES General Information See Figure 3 The Exhaust Gas Recirculation (EGR) system is used to control emissions measured at the tailpipe. Components included are the EGR valve and controls. The EGR system uses a poppet type valve to regulate the amount of exhaust gas flowing into the intake manifold. The flow path is cast into the cylinder head and does not use any external tubing. A control solenoid valve regulates the amount of vacuum to the EGR valve. A Constant Volume Control (CVC) valve provides a constant amount of vacuum to the control solenoid valve over a wide range of engine vacuum. When servicing or repairing any part of the emissions system, it is absolutely essential to check for any obvious mechanical faults or failures. Remember, a trouble code only indicates which sensor or circuit is affected by the problem. Simple mechanical faults such as a vacuum leak or poor electrical connection can cause a fault code. The EGR valve is not simply open or closed but is modulated by controlling the amount of engine vacuum to the valve diaphragm, up to a maximum of 8 in. Hg of vacuum. The EGR valve has a sensor in the top of the valve that reports valve lift to the ECU (same as ECM, 1992-95). The ECU modulates the position of the control solenoid valve to control the EGR valve lift according to an internal program. Upstream of the control solenoid valve, the CVC provides a constant supply of vacuum so EGR control is precise under all manifold vacuum conditions
