Code P1346 Saturn Description

The Camshaft Position (CMP) sensor input is used to detect an engine misfire. The Powertrain Control Module (PCM) also uses the CMP sensor signal as an input for modifying the fuel injection timing and for modifying the ignition timing.
The PCM receives information on the engine status from various engine sensors and then selects the most appropriate ignition timing settings from within the PCM's programming. The following are the most important inputs for determining ignition timing requirements:
- The engine speed
- The throttle position (TP)
- The intake air volume
- The engine coolant temperature (ECT)
- The knock sensor (KS) input

Frequently Asked Questions about P1346 Saturn Code

What does the OBDII code P1346 mean on a Saturn vehicle?

1. P1346 indicates an issue with the intake camshaft position sensor system, specifically a performance problem or misalignment detected by the engine control module (ECM). 2.

What are the common symptoms of code P1346 in a Saturn?

Symptoms may include a rough idle, reduced engine performance, poor fuel economy, difficulty starting, and the check engine light turning on. 3.

What causes the P1346 code to appear in a Saturn?

Common causes include a faulty intake camshaft position sensor, timing chain/belt issues, oil flow problems, or a malfunctioning variable valve timing (VVT) solenoid. 4.

Can low oil levels cause the P1346 code on a Saturn?

Yes, low or dirty oil can affect the VVT system and camshaft timing, potentially triggering the P1346 code. 5.

How do I fix the P1346 code on my Saturn?

Repairs may involve replacing the intake camshaft position sensor, inspecting and adjusting the timing chain/belt, cleaning or replacing the VVT solenoid, or addressing oil-related issues. 6.

Is it safe to drive a Saturn with the P1346 code?

Driving with this code is not recommended, as it can lead to reduced performance, potential engine damage, and unsafe driving conditions. 7.

How can a mechanic diagnose the P1346 code?

A mechanic will use an OBDII scanner to read the code, inspect the intake camshaft position sensor and wiring, check the timing chain/belt alignment, and assess the VVT system. 8.

Can a faulty camshaft position sensor alone trigger the P1346 code?

Yes, a malfunctioning or failing camshaft position sensor can cause the ECM to detect incorrect timing and set the P1346 code. 9.

What tools are needed to troubleshoot the P1346 code in a Saturn?

Common tools include an OBDII scanner, a multimeter to test electrical connections, and basic hand tools for sensor or component removal. 10.

How much does it cost to repair the P1346 code on a Saturn?

Repair costs vary, but replacing a camshaft position sensor typically ranges from $100 to $300, while timing chain or VVT system repairs can be more expensive.
