ACTIONS: • If you only have DTC P0340, replace only Bank 1 CMP (Camshaft Position) Sensor. • If you only have DTC P0345, replace only Bank 2 CMP (Camshaft Position) Sensor. • If you have both codes, replace both sensors. • For a “hard to start warm” incident, replace both sensors, even if you have no codes. Refer to sections EC and EM in the correct Service Manual for sensor replacement information. If replacement of the sensors does not solve your incident, go back to ASIST for further diagnostic and repair information.

2005 Nissan Quest Malfunction Indicator Light (MIL) is ON

1 Check scan data for fuel trims to see if the system is in proper fuel control – look for 0% plus or minus 10% in generic or 90 – 110 % alpha in manufacture specific. 2. Verify there are no exhaust leaks. 3. Drive the vehicle and check the bank 1 rear O2 sensor activity on the scan tool or with a voltmeter to see if the bank 1 rear O2 sensor is cross counting like a typical front O2 sensor would. Potential Causes: Catalytic Converter Tech Tips: If in manufacture specific with the scan tool, Nissan displays fuel trims in alpha. 100% alpha is the same as 0% fuel trim. This vehicle has front air fuel ratio sensors – not O2 sensors. Bank 1 is the firewall bank. Bank 2 is the radiator bank. Before the catalytic converter lights off, the rear O2 sensor voltage is usually down around 0.2 – 0.4 volts or so but when the catalytic converter lights off, it uses up a lot of the oxygen so the rear O2 sensor voltage will typically reads around 0.6 – 0.7 volts and have some movement but not a lot of movement and should not cross count above and below 0.5 volts. The catalytic converter is covered under the 8 year 80,000 mile federal emissions warranty.

1997 Chevrolet Chevy K Pickup DTC P0152 HO2S Circuit High Voltage Bank 2 Sensor 1 Repair Manual

The number below refers to the step number on the diagnostic table. 2. This test determines if the conditions exist in order to set the DTC P0152. 3. If the HO2S (Bank 2, Sensor 1) is intrnally shorted, the HO2S (Bank 2, Sensor 1) voltage displayed on a scan tool will be over 1.0 volt (1000 mV). Important: Before clearing DTCs, use the scan tool in order to record the Freeze Frame and the Failure Records for reference. This data will be lost when the Clear DTC Information function is used. Was the Powertrain On-Board Diagnostic (OBD) System Check performed? — Go to Step 2 Go to Powertrain On Board Diagnostic (OBD) System Check 2 1. Connect the scan tool. 2. Run the engine at the normal operating temperature. 3. Place the vehicle in park or neutral. 4. Apply the parking brake. 5. Increase the engine speed to the specified value. Does the scan tool data display indicate HO2S sensor voltage fixed above the specified value? 1200 RPM 0.976 V (976 mV) Go to Step 3 Go to Step 4 3 1. Disconnect the HO2S. 2. Turn on the ignition while leaving the engine OFF. 3. Turn ON the ignition leaving the engine off. Does the scan tool data display indicate the HO2S voltage near the specified value? 400 mV) Go to Step 6 Go to Step 5 4 The DTC is intermittent. Are any additional DTCs set? — Go to the applicable DTC table Go to Diagnostic Aids 5 1. Check for a short to voltage in the HO2S Signal circuit. 2. If a problem is found, repair the circuit as necessary. Refer to Wiring Repairs in Electrical Diagnosis. Was the HO2S Signal circuit shorted? — Go to Step 8 Go to Step 7 6 Replace the HO2S. Refer to Heated Oxygen Sensor (HO2S) Replacement . Is the action complete? — Go to Step 8 — 7 Replace the VCM. Important: When replacing the VCM, the new VCM will need to be programed. Refer to VCM Replacement/Programming . Is the action complete? — Go to Step 8 — 1. Use the scan tool in order to select the DTC and the Clear DTC Information functions.


IF YOU CONFIRM The ABS light is ON with one or more of the following DTC stored, • C1105 – RR RH Sensor 2 • C1110 – Controller Failure • C1124 – RR LH IN ABS SOL • C1126 – RR RH IN ABS SOL and/or The ABS system activates with normal braking. ACTIONS 1. Remove only the right rear brake rotor, wheel hub assembly, baffle plate and ABS wheel sensor. 2. Clean the corrosion off of the knuckle, wheel hub assembly, and baffle plate. 3.
