Oldsmobile Intrigue Camshaft Position Sensor: A Vehicle-Specific Guide (1998-2002)
Everything Intrigue owners need to know about diagnosing and replacing a faulty engine camshaft position sensor.
- Verify your engine (3.8L for 98-99, 3.5L for 99-02) as they use different sensors.
- A common symptom is a no-start condition where the engine cranks but won't fire, often with code P0340.
- Check for the outstanding ignition switch recall, as its symptoms can mimic a failed sensor.
- For reliability, choosing an OEM-grade brand like ACDelco or Delphi is highly recommended for this critical sensor.
Understanding the Camshaft Position Sensor in Your Intrigue
The 1998-2002 Oldsmobile Intrigue was equipped with two different engines, and the camshaft position sensor is specific to each one. It's crucial to identify your engine before purchasing a replacement part.
- 1998-1999 Oldsmobile Intrigue: These models primarily used the 3.8L V6 (L36) engine.
- 1999-2002 Oldsmobile Intrigue: These models used the newer 3.5L V6 (LX5) "Shortstar" DOHC engine.
A failing camshaft position sensor can cause a range of problems, from a simple check engine light to a car that won't start at all. Because its symptoms can sometimes mimic other issues, proper diagnosis is key.
Common Failure Symptoms
When the camshaft position sensor begins to fail, your Intrigue will likely let you know. Here are the most common signs reported by owners and mechanics.
Important Recall Information
All 1998-2002 Oldsmobile Intrigues were part of a major safety recall (NHTSA Campaign ID: 14V355000) for a faulty ignition switch. The defect can cause the key to move out of the 'run' position, shutting off the engine while driving. This can mimic the symptoms of a failed camshaft or crankshaft sensor, such as sudden stalling. Before replacing sensors, it's wise to ensure this recall has been performed on your vehicle.
Choosing the Right Aftermarket Sensor
For a critical electronic part like a camshaft position sensor, quality matters. While many brands are available, they generally fall into a few tiers. For GM vehicles of this era, sticking to brands with a history as original equipment (OE) suppliers is a safe bet.
Brand Quality Tiers for Your Intrigue
| Tier | Brands | Assessment |
|---|---|---|
| OEM / Premium Aftermarket | ACDelco, Delphi | These brands are often the original equipment manufacturers for General Motors. They are engineered to OE specifications and are highly recommended for reliability and fit. Choosing one of these is the closest you can get to the original factory part. |
| Quality Aftermarket | NGK/NTK, Hitachi, Standard Ignition (SMP), Walker Products | These are reputable brands known for producing quality sensors. They offer a good balance of price and performance and are a solid choice if an OEM-tier part isn't available or is outside your budget. |
| Economy / Store Brands | Dorman, Holstein, True Tech, Global Parts, various store-branded parts | These parts offer a cost-effective solution. While Dorman is a well-known brand that provides direct-fit replacements, economy-tier sensors can sometimes have a shorter lifespan compared to premium options. They can be a viable option for a budget repair, but be aware of the potential for a repeat failure sooner than with a premium part. |
Installation Guide & Location
The difficulty of this job depends on which engine your Intrigue has. Always disconnect the negative battery terminal before beginning any work.
For 3.5L V6 Engines (1999-2002):
The camshaft position sensor is relatively easy to access. It is located on the driver's side of the engine, near the top, just behind the coolant reservoir. You will need to remove the two nuts holding the coolant reservoir and move it aside to gain clear access. The sensor is held in by a single 10mm bolt.
For 3.8L V6 Engines (1998-1999):
The sensor is located on the front of the engine, on the timing cover. It is positioned just above the main crankshaft pulley (harmonic balancer) and near the power steering pump pulley. Access can be tight, but it is reachable from the top of the engine bay. It is also held in by a 10mm bolt.
Pro Tip: Lubricate the O-Ring
The new sensor will have a rubber O-ring to seal it against the engine. Before installing the new sensor, apply a small amount of clean engine oil to the O-ring. This will help it slide into place easily and prevent the O-ring from tearing during installation.
Frequently Asked Questions
Can I still drive my Intrigue with a bad camshaft position sensor?
It is not recommended. While the car may still run, you risk the engine stalling at any time, which is a serious safety hazard. You will also experience poor performance and fuel economy.
What's the difference between the camshaft and crankshaft sensors?
They are similar sensors that perform related but different jobs. The camshaft sensor tracks the valve position in the top part of the engine, while the crankshaft sensor tracks the piston position in the bottom part. The ECM needs both signals to be in sync. A failure in one can often cause similar symptoms to the other.
Will replacing the sensor fix a P0340 code?
Often, yes. A P0340 code specifically points to a problem in the camshaft position sensor circuit. However, the issue could also be with the wiring, the connector, or even the ECM itself. Always inspect the wiring and connector for damage or corrosion before replacing the sensor.
Is there a TSB for the camshaft sensor on the Intrigue?
No specific Technical Service Bulletins (TSBs) for the camshaft position sensor itself were found for the 1998-2002 Intrigue. However, for the 3.8L V6 models, there was a safety recall (NHTSA 15V-701) for oil leaks from the valve cover gasket onto the hot exhaust manifold, which could cause an engine fire. This is unrelated to sensor function but important for owners to be aware of.
Technical Specifications
OEM Part Numbers: 10456596 19245473 213-151 213-454
The sensor is a 3-pin Hall-effect sensor that reads the rotation of the camshaft. The correct part will be specific to either the 3.8L OHV V6 engine or the 3.5L DOHC V6 engine.
