DTC FOR VARIABLE VALVE TIMING CONTROL FUNCTION APPLIED VEHICLES: All 1997 – 2007 with Variable Valve Timing APPLIED ENGINES: VQ35; VH41, VK45; VK56 IF YOU CONFIRM The MIL is on with any of the following DTCs stored: P0011, P0014, P0021, P0024, P1110, P1135, NOTE: The engine may also have Camshaft Sprocket rattle noise and/or other engine noise. ACTION Do Not replace the variable valve timing Solenoid Valve or the Sprocket(s) without performing the complete diagnostics indicated in the EC section of the Service Manual. The first steps in the complete diagnostic is to make sure the: • Engine oil is at the operating level; add oil if needed. Refer to the Service Manual for low oil level diagnoses if needed. • Oil pressure is normal when measured with a gauge at the pressure switch port. Refer to the Service Manual for low oil pressure diagnoses if needed.

TIMING BELT Removal 1. Disconnect negative battery cable. Remove upper engine torque strut attaching bolts and remove engine torque strut. See Fig. 5 . Remove engine torque strut bracket from strut tower. On PT Cruiser (Turbo), discharge and evacuate A/C system. Disconnect A/C lines at junction block near upper timing belt cover. 2. On all models, remove upper timing belt cover bolts and remove cover. See Fig. 6 . Raise vehicle on hoist and remove right front wheel. Remove splash shield. See Fig. 7 . Remove accessory drive belts. Remove crankshaft damper. See Fig. 8 . Remove pencil strut. See Fig. 2 . Remove lower engine torque strut. See Fig. 5 . 3. Disconnect exhaust system front pipe from manifold. Disconnect A/C pressure switch at rear of compressor housing. Lower vehicle and support engine with a jack. If not done previously, discharge and evacuate A/C system. Disconnect A/C lines at junction block. Remove screw attaching ground strap to strut bracket. Remove torque strut bracket from strut tower. Remove upper radiator closure panel. Without disconnecting lines from power steering pump, remove pump and bracket and set pump aside. 4. With engine properly supported, remove right engine mount through-bolt. See Fig. 5 . Raise engine with jack until engine support bracket bolts are accessible, and remove engine support bracket. See Fig. 9 . Remove lower timing belt cover bolts and remove cover. See Fig. 6 . CAUTION: When aligning crankshaft and camshaft timing marks, always rotate engine from crankshaft. Camshaft should not be rotated after timing belt is removed, or damage to valve components may occur. CAUTION: Crankshaft sprocket TDC mark is located on the trailing edge of sprocket tooth. Failure to align trailing edge of sprocket tooth to TDC mark on oil pump housing will cause camshaft timing marks to be misaligned. 5. Before removal of timing belt, rotate crankshaft until TDC mark on oil pump housing aligns with the TDC mark on crankshaft sprocket (trailing edge of sprocket tooth). See Fig. 10 . 6. Loosen timing belt tensioner lock bolt, and insert a 6-mm Allen wrench into hexagon opening located on top plate of belt tensioner pulley. See Fig. 11 . Rotate top plate clockwise until there is enough slack in timing belt to allow for removal. If reusing old timing belt, mark belt with arrow to indicate original direction of rotation. Remove timing belt. CAUTION: If timing belt was damaged due to incorrect rotating tracking (alignment), belt tensioner pulley and bracket must be replaced as an assembly.

high/erratic idle and/or the MIL light on. In some cases, vacuum leak noise may be heard as well. There may be poor contact or loss of contact at various main ground points or electrical connections. Power steering pressure switch may be shorted with debris. Inlet manifold gasket may be leaking. Broadcast code and calibration part number may need to be updated. To correct this condition, follow the procedures outlined in this bulletin to determine proper diagnosing, inspection and correction of ground contact points for proper electrical contact, power steering pressure switch cleaning or replacement and power steering system flush, replacement of inlet manifold gasket, and/or PCM reprogramming. SERVICE PROCEDURE Please refer to the appropriate workshop manual for the correct diagnosing procedure and/or follow the service procedures outlined in this bulletin for the vehicle being serviced. 1. Inspect main ground points (refer to SB99-04-S001 for more information). P6 ground point-body [on the passenger side of engine compartment, between the battery and cruise control actuator (if equipped)]. (Figure Fig. 1 ) P10 ground point-engine (at the alternator bracket). (Figure Fig. 2 ) The 1998, 1999 or 2000 Rodeo/Amigo Electrical Troubleshooting Manual can assist in locating the vehicle ground distribution (i.e., ground contact points). Perform a voltage drop test at the main ground points. If the voltage drop test fails, then inspect and clean both the bolt and

Evaporator Temperature Switch Although compressor clutch does not normally cycle on and off, an evaporator temperature switch turns off the compressor clutch if evaporator temperature decreases to 32øF (0øC). This prevents evaporator icing. See Fig. 6. A/C Pressure Switch A/C pressure switch is a triple-pressure switch, which monitors high side pressure. See Fig. 1. If pressure decreases to less than 17.4 psi (1.2 kg/cmý), A/C pressure switch interrupts power to compressor clutch (low-pressure cutout). Switch closes when pressure increases to more than 34.8 psi (2.4 kg/cmý). If pressure increases to more than 464 psi (32.6 kg/cmý), A/C pressure switch interrupts power to compressor clutch (high-
