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.

1999-2002 CHEVROLET SILVERADO 2000-2002 CHEVROLET TAHOE, SUBURBAN 2002 CHEVROLET AVALANCHE 1999-2002 GMC SIERRA 2000-2002 GMC YUKON, YUKON XL LOCATED IN THE SEVERE CORROSION AREAS LISTED BELOW Service Procedure The following procedure provides instructions for repairing a corrosion condition where the front wheel speed sensor mounts on the front wheel bearing assembly. 1. Raise the vehicle on a suitable hoist and support as necessary. 2. Remove both front tires and wheels. 3. Compress the front brake caliper pistons. 3.1. Install a large C-clamp over the top of the caliper housing and against the back of the outboard pad. 3.2. Slowly tighten the C-clamp until the pistons are pushed completely into the caliper bores. 3.3. Remove the C-clamp from the caliper. Important: It is not necessary to remove the front brake caliper from the bracket when removing the bracket in the next step. 4. Remove the two bolts that attach the front brake caliper mounting brackets to the knuckle. Notice: Support the brake caliper with heavy mechanic’s wire, or equivalent, whenever it is separated from its mount, and the hydraulic flexible brake hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak. 5. Remove the brake caliper and bracket as an assembly and support it with heavy mechanic’s wire or equivalent. DO NOT disconnect the hydraulic brake flexible hose from the caliper. 6. Mark the relationship of the rotor to the bearing hub. 7. If equipped, remove the rotor retaining push nuts from the wheel studs


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.

LM7, L59 or L33 Engines with Cold Start Rough or Incorrect Idle, Misfire, Malfunction Indicator Lamp (MIL) or Flashing Requiring O2 Sensor Replacement

2004-2005 Cadillac Escalade 2004-2005 Chevrolet Avalanche, Silverado 1500, Suburban, Tahoe 2005 Chevrolet Silverado Hybrid (HP2) 2004-2005 GMC Sierra 1500, Yukon, Yukon XL 2005 GMC Sierra Hybrid (PH2) with Vortec 5300 5.3L V-8 Engine (VINs T, Z, B — RPOs LM7, L59, L33 Some customers may comment on a Malfunction Indicator Lamp (MIL) On or that the MIL is flashing. An actual engine misfire may or may not be felt along with an incorrect idle speed. Typically this occurs during cold winter months, on cold engine starts. Some vehicles may have been previously serviced for the same condition. Technicians may also find the following DTCs stored with the Tech 2® P0131, P0133, P0134, P0137, P0138, P0140, P0151, P0153, P0154, P0157, P1133, which may be in conjunction with P0171, P0174, P0300 and P1138. Cause Water shock occurs when water droplets are present in the exhaust. The water in the exhaust contacts the sensor element inside the HO2 sensor, causing the HO2 sensor element to crack. Correction Upon diagnostic investigation, the technician may find that the HO2 sensor requires replacement. In addition to replacing the affected HO2 sensor, these vehicles should also be reflashed with the latest PCM calibration. An updated PCM calibration will be available to dealerships as part of TIS 2000 incremental satellite update 11.0 (NAO version 25.010) or greater. Always, make sure your Tech 2 is updated with the latest software version
